Log:
MacOSX: ctypes annotation in implementation of getproxies_macosx_sysconf
getproxies_macosx_sysconf uses ctypes to call SystemConfiguration APIs. This
checkin adds ctypes annotation to specify the right argument types for the
API's that are used.
This is needed to be able to use urllib on a 64-bit system, without
annotations you'd get a hard crash.
