* Access .dex (Dalvik Executable Format) files. The code here assumes that
* the DEX file has been rewritten (byte-swapped, word-aligned) and that
* the contents can be directly accessed as a collection of C arrays. Please
* see docs/dalvik/dex-format.html for a detailed description.
* The structure and field names were chosen to match those in the DEX spec.
* It's generally assumed that the DEX file will be stored in shared memory,
* obviating the need to copy code and constant pool entries into newly
* allocated storage. Maintaining local pointers to items in the shared area
* is valid and encouraged.
* All memory-mapped structures are 32-bit aligned unless otherwise noted.

* Map the specified DEX file read-only (possibly after expanding it into a
* temp file from a Jar). Pass in a MemMapping struct to hold the info.
* If the file is an unoptimized DEX file, then byte-swapping and structural
* verification are performed on it before the memory is made read-only.
* The temp file is deleted after the map succeeds.
* This is intended for use by tools (e.g. dexdump) that need to get a
* read-only copy of a DEX file that could be in a number of different states.
* If "tempFileName" is NULL, a default value is used. The temp file is
* deleted after the map succeeds.
* If "quiet" is set, don't report common errors.
* Returns 0 (kUTFRSuccess) on success.

* Utility function to open a Zip archive, find "classes.dex", and extract
* it to a file.
