Re-implement the 'warnings' module in C (the original Python code has been
kept as backup). This will allow for using the 'warning's machinery in such
places as the parser where use of pure Python code is not possible.  Both
the ``showarning()`` and ``formatwarning()`` gain an optional 'line'
argument which is not called by default for backwards-compatibility reasons.
Setting ``warnings.showwarning()`` to an implementation that lacks support
for the ``line`` argument will raise a DeprecationWarning.

The getpass module has been improved on Unix.  It now uses /dev/tty by
default and uses stderr instead of stdout.  A GetPassWarning is issued when
input echo cannot be controlled.

Individual file objects may now be used from multiple threads at once
without fear of crashing the Python interpreter.  If file.close() is called
while an object is in use by another thread an IOError exception will be
raised and the file will not be closed.

distutils.core.run_script() makes __file__ available, so the controlled
environment will more closely mirror the typical script environment.  This
supports setup.py scripts that refer to data files.

.. section: Tests

The approach used by client/server code for obtaining ports to listen on in
network-oriented tests has been refined in an effort to facilitate running
multiple instances of the entire regression test suite in parallel without
issue. test_support.bind_port() has been fixed such that it will always
return a unique port -- which wasn't always the case with the previous
implementation, especially if socket options had been set that affected
address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT).  The new implementation of
bind_port() will actually raise an exception if it is passed an
AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or SO_REUSEPORT
socket option set.  Furthermore, if available, bind_port() will set the
SO_EXCLUSIVEADDRUSE option on the socket it's been passed.  This currently
only applies to Windows.  This option prevents any other sockets from
binding to the host/port we've bound to, thus removing the possibility of
the 'non-deterministic' behaviour, as Microsoft puts it, that occurs when a
second SOCK_STREAM socket binds and accepts to a host/port that's already
been bound by another socket.  The optional preferred port parameter to
bind_port() has been removed.  Under no circumstances should tests be hard
coding ports!

test_support.find_unused_port() has also been introduced, which will pass a
temporary socket object to bind_port() in order to obtain an unused port.
The temporary socket object is then closed and deleted, and the port is
returned.  This method should only be used for obtaining an unused port in
order to pass to an external program (i.e. the -accept [port] argument to
openssl's s_server mode) or as a parameter to a server-oriented class that
doesn't give you direct access to the underlying socket used.

Finally, test_support.HOST has been introduced, which should be used for the
host argument of any relevant socket calls (i.e. bind and connect).

The following tests were updated to following the new conventions:
test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
test_poplib, test_ftplib, test_telnetlib, test_socketserver,   test_asynchat
and test_socket_ssl.

It is now possible for multiple instances of the regression test suite to
run in parallel without issue.
