Database (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others) now accept
and return characters from the full Unicode range (Py_UCS4).

The differences from Python code are few:
- unicodedata.numeric(), unicodedata.decimal() and unicodedata.digit()
  now return the correct value for large code points
- repr() may consider more characters as printable.

It is not sure it will be beneficial, though, since process launching is
more expensive under Windows than it is under Linux.

 * Use the current filesystem encoding instead of always using utf-8
 * Enable the test on Mac OS X
 * Use TESTFN_UNENCODABLE and TESTFN_UNICODE instead of arbitrary filenames
 * To decode a filename, use strict error handler instead surrogateescape for
   mbcs encoding (on Windows)
 * Use TESTFN_UNENCODABLE (if available) for the directory name

Skip the test if no non-ascii filename can be created.

... to get the filename as a unicode object, instead of a byte string. Function
needed to support unencodable filenames. Deprecate PyModule_GetFilename() in
favor on the new function.

Encode unicode strings to the terminal encoding with backslashreplace error (as
Python does for sys.stderr) before writing them to sys.stdout. It fixes
UnicodeEncodeError on writing non-ascii characters in an ascii terminal (C
locale: ASCII encoding).

and `gzip.decompress`.  Original patch by Anand B. Pillai.

fix issue #8866: parameters passed to socket.getaddrinfo can now be specified as single keyword arguments.

Issue #8202: Set sys.argv[0] to -m rather than -c while searching for the module to execute. Also updates all the cmd_line_script tests to validate the setting of sys.path[0] and the current working directory

Another attempt at pacifying the windows buildbots by ignoring all the variable information in the dis.code_info tests

Address XXX comment in dis.py: inspect.py now attempts to reuse the dis.py compiler flag values before resorting to defining its own

Document and test the resolution of issue 3445 (tolerate missing attributes in functools.update_wrapper, previously implemented as a side effect of the __annotations__ copying patch) and implement issue 9567 (add a __wrapped__ attribute when using update_wrapper)
