Summary: PEP 269 Implementation

Initial Comment:
The following are files for the implementation of PEP
269.  The primary changes to the core involve moving
required pgen modules from the pgen only module list to
the Python library module list in Makefile.pre.in. 
Some of the modules required better memory allocation
and management and the corresponding deallocators are
in the Python extension module (maybe these should be
moved into the pgen modules in Parser).

Initially included are two implementations.  The first
is a basic implementation that follows the PEP API more
or less.  The second (currently unfinished)
implementation provides a more object oriented
interface to the extension module.

Please note there are some commented out modifications
to setup.py as I was unable to build the extension
module(s) automagically.  For some reason the linker I
was using (on a BSD box) complained that it couldn't
find the _Py_pgen symbol, even though I verified its
existence in the new Python library.  Maybe it is
checking against an older Python library on the system?

Things to be done (as of initial submission) include
resolving on a single interface, documenting the one
true interface, and finishing any unimplemented
routines (such as are found in the OO implementation).

In the final integration, a pgenmodule.c file should be
added to the Modules directory in the main distribution.

Closed. Jon, if you're still interested in this, upload
something new and reopen the patch (or I can do that).

Lowering priority until Jon has his next version ready.

Cool. Maybe I'll get to it, maybe not. :-(

Guido, as per my private message, I'll attempt to submit
another patch by the end of the month, pending resumption of
"work" on the 23rd.  Commitment of the memory allocation
patch is fine, and any future patches would be against the
updated pgen code (I don't have commit permissions, so
someone else will have to do this possibly.)

I looked a bit, and it's very raw - the author admits that.
Jon, are you still working on this? Do you have a more
polished version?

Maybe we can separate out the memory allocation patches and
commit these already? They don't break anything.

I guess I'm going to hve to look at this to pronounce...
