Get rid of backward compatibility modules. Do this fairly early in the 2.3 cycle so we don't shoot ourselves in the foot later.

The deprecation is now listed in PEP 4.

not-GPL-compatible to GPL-compatible, with a footnote explaining that
RMS disagrees.  I'm not going to discuss this further -- both sides
(CNRI and RMS) will argue their POV till they're blue in the face.

Got rid of ifdefs for long-obsolete GUSI versions and other stuff that is now standard (appearance, interned strings)

This is nice for use with "make TESTOPTS='-u all' test".

The bug report pointed out a bogosity in the comment block explaining
thread safety for arena management.  Repaired that comment, repaired a
couple others while I was at it, and added an assert.

_PyMalloc_DebugRealloc:  If this needed to get more memory, but couldn't,
it erroneously freed the original memory.  Repaired that.

This is for 2.3 only (unless we decide to backport the new pymalloc).

Different .pyc icon - use "paler" colors to better differentiate it from the main .py icon.  As discussed with Tim (prompted by cl.lpy posting)

(2.2 bugfix candidate?)

non-us-ascii character sets in headers and bodies.  Some API changes
(with DeprecationWarnings for the old APIs).  Better RFC-compliant
implementations of base64 and quoted-printable.

Updated test cases.  Documentation updates to follow (after I finish
writing them ;).

Update description of PyType_Check().

Move imports to top

happen in a well-defined conversion.
