PyGC_Dump() -> _PyGC_Dump()

exportable module attributes (they're attributes on the IMAP class).
Fixed the case typo on Time2Internaldate.

Does anybody run the test suite any more? <wink>

   Get platform-specific modules right on Cygwin
   Getting a string value for the platform has been factored out into
   get_platform()

Bump version number

Added an attribute runtimemodel, which is either "ppc" or "carbon" and is the runtime model of the current interpreter. Will have to ad another value later for real MacOSX MachO, I guess.

Generate Carbon as well as classic PPC plugin projects. This module is finally paying back the investment in it!

Fixes bug #121706.

Added Matthias Neeracher and Alexandre Parenteau to the "thank you" list. This should have been done _ages_ ago for Matthias! Shame shame!!

Upped the default memory size to a whopping 24Mb, which is needed to make the autotests run. Sigh. User with low-memory systems will have to adapt the setting.

Py_Initialize()/Py_Finalize() loop leaks.

- allow an optional 3rd argument which is the loop count.  -1 means
  infloop (the default).

- Add a setting of Py_NoSiteFlag=1, but leave it commented out by
  default.

- set VERSION to 2.1

- change blddir to ../.. since that seems more common than the old
  value (at least for my debugging session).

WITH_CYCLE_GC.

PyGC_Dump(): Wrap this in a #ifdef WITH_CYCLE_GC.

pull it in automatically.

PyObject_Dump(): New function that is useful when debugging Python's C
runtime.  In something like gdb it can be a pain to get some useful
information out of PyObject*'s.  This function prints the str() of the
object to stderr, along with the object's refcount and hex address.

PyGC_Dump(): Similar to PyObject_Dump() but knows how to cast from the
garbage collector prefix back to the PyObject* structure.

[See Misc/gdbinit for some useful gdb hooks]

none_dealloc(): Rather than SEGV if we accidentally decref None out of
existance, we assign None's and NotImplemented's destructor slot to
this function, which just calls abort().

module__doc__: Document the Warning subclass heirarchy.

make_class(): Added a "goto finally" so that if populate_methods()
fails, the return status will be -1 (failure) instead of 0 (success).

fini_exceptions(): When decref'ing the static pointers to the
exception classes, clear out their dictionaries too.  This breaks a
cycle from class->dict->method->class and allows the classes with
unbound methods to be reclaimed.  This plugs a large memory leak in a
common Py_Initialize()/dosomething/Py_Finalize() loop.

sources. So far only runs under unix, but what gives:-)
