Add internal APIs for portable path manipulation
k5_path_split separates a path into dirname and basename.
k5_path_join joins two paths.
k5_path_isabs determines if a path is absolute.
All three functions follow the Python path function semantics.
Currently the test module doesn't run in the Windows build, but the
Windows path semantics are tested in the Unix build using specially
built objects.
