Better test for skipping project creation: the project file should also exist and be newer than the xml file, and the .exp should exist.

Allow pickle.py to be using with Jython unicode strings

test_class.py.

also added unicodename_db.h dependency to ucnhash.

(cosmetic whitespace change).

supposed to be declared in system include files (with a proper prototype.)
Should be moved to a platform-specific block if anyone finds out which
broken platforms need it :-)

to build *all* tables in makeunicodedata.py.

Added CarbonAccessors.o to the non-carbon targets, and probably a few minor things having to do with Python 2.1a1.

Added carbon targets (mainly placeholders at the moment).

Added a force option (to force project generation, the default is now to only generate if different).
Try to convert all search paths to relative.

Don't generate project if the XML file already exists and is identical to what we've generated. Overridable with a "force" argument to mkproject().

Suggested by Kevin Jacobs in bug report #129417.

Participate in garbage collection if available.
Potentially decref handlers in clear_handlers.
Partially reindent.
Put synthetic frame object on the stack to support better error output.
Expose Python codecs to pyexpat.
Add new Expat 1.2 handlers and API.
Fix memory leak: release self->handlers.
Do not expect PyModule_AddObject and PyModule_AddStringConstant in 2.0b1.
Raise exception in ParseFile.

pythonrun.c:  In Py_Finalize, don't reset the initialized flag until after
the exit funcs have run.
atexit.py:  in _run_exitfuncs, mutate the list of pending calls in a
threadsafe way.  This wasn't a contributor to bug 128475, it just burned
my eyeballs when looking at that bug.

added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.

pdb (pdb calls it 'where').  Added 'bt' as an alias for 'where'.
