This patch trims down the Python core on Darwin by making it
independent of CoreFoundation and CoreServices. It does this by:

Changed linker flags in configure/configure.in
Removed the unused PyMac_GetAppletScriptFile
Moved the implementation of PyMac_StrError to the MacOS module
Moved the implementation of PyMac_GetFullPathname to the
Carbon.File module
