* 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) git-svn-id: svn://10.0.0.236/branches/DOM_AGNOSTIC_BRANCH@179616 18797224-902f-48f8-a5cc-f745e15eee43
