* pyxpcom.dll/.so holds the core library. _xpcom module becomes a thin
wrapper around the DLL, and the module loader gets the main loader logic
back.
* Don't globally block pending deprecation warnings in Python 2.4 -
also fix a few places where 2.3 and 2.4 behaved differently.
* Add the start of logging module support, pending approval from the mailing list.
* Expose NS_GetComponentRegistrar so regxpcom.py works again.
* 'make check' now runs the test suite (like it does for various other parts of the moz tree)
