[Rpm-maint] [PATCH 07/15] Use macros to hide "int" implementation differences between Python 2 and 3

[David Malcolm]

On Python 3, use macros to alias all usage of PyInt_ to PyLong_ equivalents,
as the former no longer exists.

Likewise, the "cmpfunc" typedef no longer exists; introduce a dummy definition
to enable our code to compile
