- Added a debug class variable to enable parser debugging.

or v.v.

most of the work.  In particular, if the underlying realloc is able to
grow the memory block in place, great (this routine used to do a fresh
malloc + memcpy every time a block grew).  BTW, I'm not so keen here on
avoiding possible quadratic-time realloc patterns as I am on making
the debug pymalloc more invisible (the more it uses memory "just like"
the underlying allocator, the better the chance that a suspected memory
corruption bug won't vanish when the debug malloc is turned on).

prefix.  These symbols are private to the file, and the PYMALLOC_ gets
in the way (overly long code lines, comments, and error messages).

PyMem_{Del, DEL} doesn't work yet (compilation problems).

pyport.h:  _PyMem_EXTRA is gone.

pmem.h:  Repaired comments.  PyMem_{Malloc, MALLOC} and
PyMem_{Realloc, REALLOC} now make the same x-platform guarantees when
asking for 0 bytes, and when passing a NULL pointer to the latter.

object.c:  PyMem_{Malloc, Realloc} just call their macro versions
now, since the latter take care of the x-platform 0 and NULL stuff
by themselves now.

pypcre.c, grow_stack():  So sue me.  On two lines, this called
PyMem_RESIZE to grow a "const" area.  It's not legit to realloc a
const area, so the compiler warned given the new expansion of
PyMem_RESIZE.  It would have gotten the same warning before if it
had used PyMem_Resize() instead; the older macro version, but not the
function version, silently cast away the constness.  IMO that was a wrong
thing to do, and the docs say the macro versions of PyMem_xyz are
deprecated anyway.  If somebody else is resizing const areas with the
macro spelling, they'll get a warning when they recompile now too.

all the same within the #ifdef WITH_PYMALLOC block.

PyMalloc_ prefix and use PyObject_ instead.  I'm not sure about the
debugging functions.  Perhaps they should stay as PyMalloc_.

PyObject_Del and PyObject_GC_Del can now be used as a function

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.

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)
