util.h: Utility macros for handling different Python APIs.

If we are in py3k, a IS_PY3K symbol is defined. Apart from that, byte strings
use the API defined in Python 2.6+ (_?PyBytes_.*). For Python < 2.6, the bytes
API is defined accordingly for mercurial usage (shameless copy from
bytesobject.h from Python's code). Some macros were backported from 2.6, as
inspired by rPath's pycompat.h.
