-  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
-  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit.  Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by
-  one.  If we call the above polynomial p, and represent a byte as the
-  polynomial q, also with the lowest power in the most significant bit (so the
-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder.  The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
-  x (which is shifting right by one and adding x^32 mod p if the bit shifted
-  out is a one).  We start with the highest power (least significant bit) of
-  q and repeat for all eight bits of q.
-
-  The first table is simply the CRC of all possible eight bit values.  This is
-  all the information needed to generate CRCs on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.  The remaining tables
-  allow for word-at-a-time CRC calculation for both big-endian and little-
-  endian machines, where a word is four bytes.

-   Decode literal, length, and distance codes and write out the resulting
-   literal and match bytes until either not enough input or output is
-   available, an end-of-block is encountered, or a data error is encountered.
-   When large enough input and output buffers are supplied to inflate(), for
-   example, a 16K input buffer and a 64K output buffer, more than 95% of the
-   inflate execution time is spent in this routine.
-
-   Entry assumptions:
-
-        state->mode == LEN
-        strm->avail_in >= 6
-        strm->avail_out >= 258
-        start >= strm->avail_out
-        state->bits < 8
-
-   On return, state->mode is one of:
-
-        LEN -- ran out of enough output space or enough available input
-        TYPE -- reached end of block code, inflate() to interpret next block
-        BAD -- error in block data
-
-   Notes:
-
-    - The maximum input bits used by a length/distance pair is 15 bits for the
-      length code, 5 bits for the length extra, 15 bits for the distance code,
-      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
-      Therefore if strm->avail_in >= 6, then there is enough input to avoid
-      checking for available input while decoding.
-
-    - The maximum bytes that a single length/distance pair can output is 258
-      bytes, which is the maximum length that can be coded.  inflate_fast()
-      requires strm->avail_out >= 258 for each loop to avoid checking for
-      output space.

-/* inflate.c -- zlib decompression
- * Copyright (C) 1995-2016 Mark Adler
- * For conditions of distribution and use, see copyright notice in zlib.h
- */
-
-/*
- * Change history:
- *
- * 1.2.beta0    24 Nov 2002
- * - First version -- complete rewrite of inflate to simplify code, avoid
- *   creation of window when not needed, minimize use of window when it is
- *   needed, make inffast.c even faster, implement gzip decoding, and to
- *   improve code readability and style over the previous zlib inflate code
- *
- * 1.2.beta1    25 Nov 2002
- * - Use pointers for available input and output checking in inffast.c
- * - Remove input and output counters in inffast.c
- * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
- * - Remove unnecessary second byte pull from length extra in inffast.c
- * - Unroll direct copy to three copies per loop in inffast.c
- *
- * 1.2.beta2    4 Dec 2002
- * - Change external routine names to reduce potential conflicts
- * - Correct filename to inffixed.h for fixed tables in inflate.c
- * - Make hbuf[] unsigned char to match parameter type in inflate.c
- * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
- *   to avoid negation problem on Alphas (64 bit) in inflate.c
- *
- * 1.2.beta3    22 Dec 2002
- * - Add comments on state->bits assertion in inffast.c
- * - Add comments on op field in inftrees.h
- * - Fix bug in reuse of allocated window after inflateReset()
- * - Remove bit fields--back to byte structure for speed
- * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
- * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
- * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
- * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
- * - Use local copies of stream next and avail values, as well as local bit
- *   buffer and bit count in inflate()--for speed when inflate_fast() not used
- *
- * 1.2.beta4    1 Jan 2003
- * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
- * - Move a comment on output buffer sizes from inffast.c to inflate.c
- * - Add comments in inffast.c to introduce the inflate_fast() routine
- * - Rearrange window copies in inflate_fast() for speed and simplification
- * - Unroll last copy for window match in inflate_fast()
- * - Use local copies of window variables in inflate_fast() for speed
- * - Pull out common wnext == 0 case for speed in inflate_fast()
- * - Make op and len in inflate_fast() unsigned for consistency
- * - Add FAR to lcode and dcode declarations in inflate_fast()
- * - Simplified bad distance check in inflate_fast()
- * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
- *   source file infback.c to provide a call-back interface to inflate for
- *   programs like gzip and unzip -- uses window as output buffer to avoid
- *   window copying
- *
- * 1.2.beta5    1 Jan 2003
- * - Improved inflateBack() interface to allow the caller to provide initial
- *   input in strm.
- * - Fixed stored blocks bug in inflateBack()
- *
- * 1.2.beta6    4 Jan 2003
- * - Added comments in inffast.c on effectiveness of POSTINC

-   inflate() uses a state machine to process as much input data and generate as
-   much output data as possible before returning.  The state machine is
-   structured roughly as follows:
-
-    for (;;) switch (state) {
-    ...
-    case STATEn:
-        if (not enough input data or output space to make progress)
-            return;
-        ... make progress ...
-        state = STATEm;
-        break;
-    ...
-    }
-
-   so when inflate() is called again, the same case is attempted again, and
-   if the appropriate resources are provided, the machine proceeds to the
-   next state.  The NEEDBITS() macro is usually the way the state evaluates
-   whether it can proceed or should return.  NEEDBITS() does the return if
-   the requested bits are not available.  The typical use of the BITS macros
-   is:
-
-        NEEDBITS(n);
-        ... do something with BITS(n) ...
-        DROPBITS(n);
-
-   where NEEDBITS(n) either returns from inflate() if there isn't enough
-   input left to load n bits into the accumulator, or it continues.  BITS(n)
-   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
-   the low n bits off the accumulator.  INITBITS() clears the accumulator
-   and sets the number of available bits to zero.  BYTEBITS() discards just
-   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
-   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
-
-   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
-   if there is no input available.  The decoding of variable length codes uses
-   PULLBYTE() directly in order to pull just enough bytes to decode the next
-   code, and no more.
-
-   Some states loop until they get enough input, making sure that enough
-   state information is maintained to continue the loop where it left off
-   if NEEDBITS() returns in the loop.  For example, want, need, and keep
-   would all have to actually be part of the saved state in case NEEDBITS()
-   returns:
-
-    case STATEw:
-        while (want < need) {
-            NEEDBITS(n);
-            keep[want++] = BITS(n);
-            DROPBITS(n);
-        }
-        state = STATEx;
-    case STATEx:
-
-   As shown above, if the next state is also the next case, then the break
-   is omitted.
-
-   A state may also return if there is not enough output space available to
-   complete that state.  Those states are copying stored data, writing a
-   literal byte, and copying a matching string.
-
-   When returning, a "goto inf_leave" is used to update the total counters,
-   update the check value, and determine whether any progress has been made
-   during that inflate() call in order to return the proper return code.
-   Progress is defined as a change in either strm->avail_in or strm->avail_out.
-   When there is a window, goto inf_leave will update the window with the last
-   output written.  If a goto inf_leave occurs in the middle of decompression
-   and there is no window currently, goto inf_leave will create one and copy
-   output to the window for the next call of inflate().
-
-   In this implementation, the flush parameter of inflate() only affects the
-   return code (per zlib.h).  inflate() always writes as much as possible to
-   strm->next_out, given the space available and the provided input--the effect
-   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
-   the allocation of and copying into a sliding window until necessary, which
-   provides the effect documented in zlib.h for Z_FINISH when the entire input
-   stream available.  So the only thing the flush parameter actually does is:
-   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
-   will return Z_BUF_ERROR if it has not reached the end of the stream.

-       code lengths are lens[0..codes-1].  Each length corresponds to the
-       symbols 0..codes-1.  The Huffman code is generated by first sorting the
-       symbols by length from short to long, and retaining the symbol order
-       for codes with equal lengths.  Then the code starts with all zero bits
-       for the first code of the shortest length, and the codes are integer
-       increments for the same length, and zeros are appended as the length
-       increases.  For the deflate format, these bits are stored backwards
-       from their more natural integer increment ordering, and so when the
-       decoding tables are built in the large loop below, the integer codes
-       are incremented backwards.
-
-       This routine assumes, but does not check, that all of the entries in
-       lens[] are in the range 0..MAXBITS.  The caller must assure this.
-       1..MAXBITS is interpreted as that code length.  zero means that that
-       symbol does not occur in this code.
-
-       The codes are sorted by computing a count of codes for each length,
-       creating from that a table of starting indices for each length in the
-       sorted table, and then entering the symbols in order in the sorted
-       table.  The sorted table is work[], with that space being provided by
-       the caller.
-
-       The length counts are used for other purposes as well, i.e. finding
-       the minimum and maximum length codes, determining if there are any
-       codes at all, checking for a valid set of lengths, and looking ahead
-       at length counts to determine sub-table sizes when building the

-    The 'zlib' compression library provides in-memory compression and
-  decompression functions, including integrity checks of the uncompressed data.
-  This version of the library supports only one compression method (deflation)
-  but other algorithms will be added later and will have the same stream
-  interface.
-
-    Compression can be done in a single step if the buffers are large enough,
-  or can be done by repeated calls of the compression function.  In the latter
-  case, the application must provide more input and/or consume the output
-  (providing more output space) before each call.
-
-    The compressed data format used by default by the in-memory functions is
-  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
-  around a deflate stream, which is itself documented in RFC 1951.
-
-    The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio using the functions that start
-  with "gz".  The gzip format is different from the zlib format.  gzip is a
-  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
-    This library can optionally read and write gzip and raw deflate streams in
-  memory as well.
-
-    The zlib format was designed to be compact and fast for use in memory
-  and on communications channels.  The gzip format was designed for single-
-  file compression on file systems, has a larger header than zlib to maintain
-  directory information, and uses a different, slower check method than zlib.
-
-    The library does not install any signal handler.  The decoder checks
-  the consistency of the compressed data, so the library should never crash
-  even in the case of corrupted input.

-   opaque value.
-
-     zalloc must return Z_NULL if there is not enough memory for the object.
-   If zlib is used in a multi-threaded application, zalloc and zfree must be
-   thread safe.  In that case, zlib is thread-safe.  When zalloc and zfree are
-   Z_NULL on entry to the initialization function, they are set to internal
-   routines that use the standard library functions malloc() and free().
-
-     On 16-bit systems, the functions zalloc and zfree must be able to allocate
-   exactly 65536 bytes, but will not be required to allocate more than this if
-   the symbol MAXSEG_64K is defined (see zconf.h).  WARNING: On MSDOS, pointers
-   returned by zalloc for objects of exactly 65536 bytes *must* have their
-   offset normalized to zero.  The default allocation function provided by this
-   library ensures this (see zutil.c).  To reduce memory requirements and avoid
-   any allocation of 64K objects, at the expense of compression ratio, compile
-   the library with -DMAX_WBITS=14 (see zconf.h).
-
-     The fields total_in and total_out can be used for statistics or progress
-   reports.  After compression, total_in holds the total size of the
-   uncompressed data and may be saved for use by the decompressor (particularly
-   if the decompressor wants to decompress everything in a single step).

-/*
-    deflate compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full.  It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-    The detailed semantics are as follows.  deflate performs one or both of the
-  following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly.  If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Generate more output starting at next_out and update next_out and avail_out
-    accordingly.  This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary.  Some output may be provided even if
-    flush is zero.
-
-    Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming more
-  output, and updating avail_in or avail_out accordingly; avail_out should
-  never be zero before the call.  The application can consume the compressed
-  output when it wants, for example when the output buffer is full (avail_out
-  == 0), or after each call of deflate().  If deflate returns Z_OK and with
-  zero avail_out, it must be called again after making room in the output
-  buffer because there might be more output pending. See deflatePending(),
-  which can be used if desired to determine whether or not there is more ouput
-  in that case.
-
-    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
-  decide how much data to accumulate before producing output, in order to
-  maximize compression.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far.  (In
-  particular avail_in is zero after the call if enough output space has been
-  provided before the call.) Flushing may degrade compression for some
-  compression algorithms and so it should be used only when necessary.  This
-  completes the current deflate block and follows it with an empty stored block
-  that is three bits plus filler bits to the next byte, followed by four bytes
-  (00 00 ff ff).
-
-    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
-  output buffer, but the output is not aligned to a byte boundary.  All of the
-  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
-  This completes the current deflate block and follows it with an empty fixed
-  codes block that is 10 bits long.  This assures that enough bytes are output
-  in order for the decompressor to finish the block before the empty fixed
-  codes block.
-
-    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
-  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
-  seven bits of the current block are held to be written as the next byte after
-  the next deflate block is completed.  In this case, the decompressor may not
-  be provided enough bits at this point in order to complete decompression of
-  the data provided so far to the compressor.  It may need to wait for the next
-  block to be emitted.  This is for advanced applications that need to control
-  the emission of deflate blocks.
-
-    If flush is set to Z_FULL_FLUSH, all output is flushed as with
-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
-  compression.
-
-    If deflate returns with avail_out == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  avail_out), until the flush is complete (deflate returns with non-zero
-  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
-  avail_out is greater than six to avoid repeated flush markers due to
-  avail_out == 0 on return.
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there was
-  enough output space.  If deflate returns with Z_OK or Z_BUF_ERROR, this
-  function must be called again with Z_FINISH and more output space (updated
-  avail_out) but no more input data, until it returns with Z_STREAM_END or an
-  error.  After deflate has returned Z_STREAM_END, the only possible operations
-  on the stream are deflateReset or deflateEnd.
-
-    Z_FINISH can be used in the first deflate call after deflateInit if all the
-  compression is to be done in a single step.  In order to complete in one
-  call, avail_out must be at least the value returned by deflateBound (see
-  below).  Then deflate is guaranteed to return Z_STREAM_END.  If not enough
-  output space is provided, deflate will not return Z_STREAM_END, and it must
-  be called again as described above.
-
-    deflate() sets strm->adler to the Adler-32 checksum of all input read
-  so far (that is, total_in bytes).  If a gzip stream is being generated, then
-  strm->adler will be the CRC-32 checksum of the input read so far.  (See
-  deflateInit2 below.)
-
-    deflate() may update strm->data_type if it can make a good guess about
-  the input data type (Z_BINARY or Z_TEXT).  If in doubt, the data is
-  considered binary.  This field is only for information purposes and does not
-  affect the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to
-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
-  if next_in or next_out was Z_NULL or the state was inadvertently written over
-  by the application), or Z_BUF_ERROR if no progress is possible (for example
-  avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not fatal, and
-  deflate() can be called again with more input and more output space to

-    inflate decompresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full.  It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-  The detailed semantics are as follows.  inflate performs one or both of the
-  following actions:
-
-  - Decompress more input starting at next_in and update next_in and avail_in
-    accordingly.  If not all input can be processed (because there is not
-    enough room in the output buffer), then next_in and avail_in are updated

-
-  - Generate more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() provides as much output as possible, until there is
-    no more input data or no more space in the output buffer (see below about
-    the flush parameter).
-
-    Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming more
-  output, and updating the next_* and avail_* values accordingly.  If the
-  caller of inflate() does not provide both available input and available
-  output space, it is possible that there will be no progress made.  The
-  application can consume the uncompressed output when it wants, for example
-  when the output buffer is full (avail_out == 0), or after each call of
-  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
-  called again after making room in the output buffer because there might be
-  more output pending.
-
-    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
-  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
-  output as possible to the output buffer.  Z_BLOCK requests that inflate()
-  stop if and when it gets to the next deflate block boundary.  When decoding
-  the zlib or gzip format, this will cause inflate() to return immediately
-  after the header and before the first block.  When doing a raw inflate,
-  inflate() will go ahead and process the first block, and will return when it
-  gets to the end of that block, or when it runs out of data.
-
-    The Z_BLOCK option assists in appending to or combining deflate streams.
-  To assist in this, on return inflate() always sets strm->data_type to the
-  number of unused bits in the last byte taken from strm->next_in, plus 64 if
-  inflate() is currently decoding the last block in the deflate stream, plus
-  128 if inflate() returned immediately after decoding an end-of-block code or
-  decoding the complete header up to just before the first byte of the deflate
-  stream.  The end-of-block will not be indicated until all of the uncompressed
-  data from that block has been written to strm->next_out.  The number of
-  unused bits may in general be greater than seven, except when bit 7 of
-  data_type is set, in which case the number of unused bits will be less than
-  eight.  data_type is set as noted here every time inflate() returns for all
-  flush options, and so can be used to determine the amount of currently
-  consumed input in bits.
-
-    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
-  end of each deflate block header is reached, before any actual data in that
-  block is decoded.  This allows the caller to determine the length of the
-  deflate block header for later use in random access within a deflate block.
-  256 is added to the value of strm->data_type when inflate() returns
-  immediately after reaching the end of the deflate block header.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error.  However if all decompression is to be performed in a single step (a
-  single call of inflate), the parameter flush should be set to Z_FINISH.  In
-  this case all pending input is processed and all pending output is flushed;
-  avail_out must be large enough to hold all of the uncompressed data for the
-  operation to complete.  (The size of the uncompressed data may have been
-  saved by the compressor for this purpose.)  The use of Z_FINISH is not
-  required to perform an inflation in one step.  However it may be used to
-  inform inflate that a faster approach can be used for the single inflate()
-  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
-  stream completes, which reduces inflate's memory footprint.  If the stream
-  does not complete, either because not all of the stream is provided or not
-  enough output space is provided, then a sliding window will be allocated and
-  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
-  been used.
-
-     In this implementation, inflate() always flushes as much output as
-  possible to the output buffer, and always uses the faster approach on the
-  first call.  So the effects of the flush parameter in this implementation are
-  on the return value of inflate() as noted below, when inflate() returns early
-  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
-  memory for a sliding window when Z_FINISH is used.
-
-     If a preset dictionary is needed after this call (see inflateSetDictionary
-  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
-  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
-  strm->adler to the Adler-32 checksum of all output produced so far (that is,
-  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
-  below.  At the end of the stream, inflate() checks that its computed Adler-32
-  checksum is equal to that saved by the compressor and returns Z_STREAM_END
-  only if the checksum is correct.
-
-    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
-  deflate data.  The header type is detected automatically, if requested when
-  initializing with inflateInit2().  Any information contained in the gzip
-  header is not retained unless inflateGetHeader() is used.  When processing
-  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
-  produced so far.  The CRC-32 is checked against the gzip trailer, as is the
-  uncompressed length, modulo 2^32.
-
-    inflate() returns Z_OK if some progress has been made (more input processed
-  or more output produced), Z_STREAM_END if the end of the compressed data has
-  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-  corrupted (input stream not conforming to the zlib format or incorrect check
-  value, in which case strm->msg points to a string with a more specific
-  error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
-  next_in or next_out was Z_NULL, or the state was inadvertently written over
-  by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
-  if no progress was possible or if there was not enough room in the output
-  buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
-  inflate() can be called again with more input and more output space to
-  continue decompressing.  If Z_DATA_ERROR is returned, the application may
-  then call inflateSync() to look for a good compression block if a partial
-  recovery of the data is to be attempted.

-
-     This is another version of deflateInit with more compression options.  The
-   fields next_in, zalloc, zfree and opaque must be initialized before by the
-   caller.
-
-     The method parameter is the compression method.  It must be Z_DEFLATED in
-   this version of the library.
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library.  Larger values of this parameter result in better
-   compression at the expense of memory usage.  The default value is 15 if
-   deflateInit is used instead.
-
-     For the current implementation of deflate(), a windowBits value of 8 (a
-   window size of 256 bytes) is not supported.  As a result, a request for 8
-   will result in 9 (a 512-byte window).  In that case, providing 8 to
-   inflateInit2() will result in an error when the zlib header with 9 is
-   checked against the initialization of inflate().  The remedy is to not use 8
-   with deflateInit2() with this initialization, or at least in that case use 9
-   with inflateInit2().
-
-     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
-   determines the window size.  deflate() will then generate raw deflate data
-   with no zlib header or trailer, and will not compute a check value.
-
-     windowBits can also be greater than 15 for optional gzip encoding.  Add
-   16 to windowBits to write a simple gzip header and trailer around the
-   compressed data instead of a zlib wrapper.  The gzip header will have no
-   file name, no extra data, no comment, no modification time (set to zero), no
-   header crc, and the operating system will be set to the appropriate value,
-   if the operating system was determined at compile time.  If a gzip stream is
-   being written, strm->adler is a CRC-32 instead of an Adler-32.
-
-     For raw deflate or gzip encoding, a request for a 256-byte window is
-   rejected as invalid, since only the zlib header provides a means of
-   transmitting the window size to the decompressor.
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state.  memLevel=1 uses minimum memory but is
-   slow and reduces compression ratio; memLevel=9 uses maximum memory for
-   optimal speed.  The default value is 8.  See zconf.h for total memory usage
-   as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm.  Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match), or Z_RLE to limit match distances to one (run-length
-   encoding).  Filtered data consists mostly of small values with a somewhat
-   random distribution.  In this case, the compression algorithm is tuned to
-   compress them better.  The effect of Z_FILTERED is to force more Huffman
-   coding and less string matching; it is somewhat intermediate between
-   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
-   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
-   strategy parameter only affects the compression ratio but not the
-   correctness of the compressed output even if it is not set appropriately.
-   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
-   decoder for special applications.
-
-     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
-   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
-   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
-   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is
-   set to null if there is no error message.  deflateInit2 does not perform any
-   compression: this will be done by deflate().

-     This is another version of inflateInit with an extra parameter.  The

-   before by the caller.
-
-     The windowBits parameter is the base two logarithm of the maximum window
-   size (the size of the history buffer).  It should be in the range 8..15 for
-   this version of the library.  The default value is 15 if inflateInit is used
-   instead.  windowBits must be greater than or equal to the windowBits value
-   provided to deflateInit2() while compressing, or it must be equal to 15 if
-   deflateInit2() was not used.  If a compressed stream with a larger window
-   size is given as input, inflate() will return with the error code
-   Z_DATA_ERROR instead of trying to allocate a larger window.
-
-     windowBits can also be zero to request that inflate use the window size in
-   the zlib header of the compressed stream.
-
-     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
-   determines the window size.  inflate() will then process raw deflate data,
-   not looking for a zlib or gzip header, not generating a check value, and not
-   looking for any check values for comparison at the end of the stream.  This
-   is for use with other formats that use the deflate compressed data format
-   such as zip.  Those formats provide their own check values.  If a custom
-   format is developed using the raw deflate format for compressed data, it is
-   recommended that a check value such as an Adler-32 or a CRC-32 be applied to
-   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
-   most applications, the zlib format should be used as is.  Note that comments
-   above on the use in deflateInit2() applies to the magnitude of windowBits.
-
-     windowBits can also be greater than 15 for optional gzip decoding.  Add
-   32 to windowBits to enable zlib and gzip decoding with automatic header
-   detection, or add 16 to decode only the gzip format (the zlib format will
-   return a Z_DATA_ERROR).  If a gzip stream is being decoded, strm->adler is a
-   CRC-32 instead of an Adler-32.  Unlike the gunzip utility and gzread() (see
-   below), inflate() will not automatically decode concatenated gzip streams.
-   inflate() will return Z_STREAM_END at the end of the gzip stream.  The state

-     inflateBack() does a raw inflate with a single call using a call-back
-   interface for input and output.  This is potentially more efficient than
-   inflate() for file i/o applications, in that it avoids copying between the
-   output and the sliding window by simply making the window itself the output
-   buffer.  inflate() can be faster on modern CPUs when used with large
-   buffers.  inflateBack() trusts the application to not change the output
-   buffer passed by the output function, at least until inflateBack() returns.
-
-     inflateBackInit() must be called first to allocate the internal state
-   and to initialize the state with the user-provided window buffer.
-   inflateBack() may then be used multiple times to inflate a complete, raw
-   deflate stream with each call.  inflateBackEnd() is then called to free the
-   allocated state.
-
-     A raw deflate stream is one with no zlib or gzip header or trailer.
-   This routine would normally be used in a utility that reads zip or gzip
-   files and writes out uncompressed files.  The utility would decode the
-   header and process the trailer on its own, hence this routine expects only
-   the raw deflate stream to decompress.  This is different from the default
-   behavior of inflate(), which expects a zlib header and trailer around the
-   deflate stream.
-
-     inflateBack() uses two subroutines supplied by the caller that are then
-   called by inflateBack() for input and output.  inflateBack() calls those
-   routines until it reads a complete deflate stream and writes out all of the
-   uncompressed data, or until it encounters an error.  The function's
-   parameters and return types are defined above in the in_func and out_func
-   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
-   number of bytes of provided input, and a pointer to that input in buf.  If
-   there is no input available, in() must return zero -- buf is ignored in that
-   case -- and inflateBack() will return a buffer error.  inflateBack() will
-   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
-   out() should return zero on success, or non-zero on failure.  If out()
-   returns non-zero, inflateBack() will return with an error.  Neither in() nor
-   out() are permitted to change the contents of the window provided to
-   inflateBackInit(), which is also the buffer that out() uses to write from.
-   The length written by out() will be at most the window size.  Any non-zero
-   amount of input may be provided by in().
-
-     For convenience, inflateBack() can be provided input on the first call by
-   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
-   in() will be called.  Therefore strm->next_in must be initialized before
-   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
-   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
-   must also be initialized, and then if strm->avail_in is not zero, input will
-   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
-
-     The in_desc and out_desc parameters of inflateBack() is passed as the
-   first parameter of in() and out() respectively when they are called.  These
-   descriptors can be optionally used to pass any information that the caller-
-   supplied in() and out() functions need to do their job.
-
-     On return, inflateBack() will set strm->next_in and strm->avail_in to
-   pass back any unused input that was provided by the last in() call.  The
-   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
-   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
-   in the deflate stream (in which case strm->msg is set to indicate the nature
-   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
-   In the case of Z_BUF_ERROR, an input or output error can be distinguished
-   using strm->next_in which will be Z_NULL only if in() returned an error.  If
-   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
-   non-zero.  (in() will always be called before out(), so strm->next_in is
-   assured to be defined if out() returns non-zero.)  Note that inflateBack()
-   cannot return Z_OK.

-
-     "a" can be used instead of "w" to request that the gzip stream that will
