[Python-Dev] Add Py_off_t and related APIs?

I see.

I would do this through a converter function (O&), but yes,
making it private to the io library sounds about right. Who
else would benefit from it?

If we start with that, we end up with ParseTuple formats for
uid_t, gid_t, pid_t, and the other dozen integral types that
POSIX has invented.
