SF patch #1035255: Remove CoreServices / CoreFoundation dependencies in core
(Contributed by Bob Ippolito.) 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
