This will also drastically simplify the work of tools like pyp2rpm,
since instead of having to do crazy processing of module names, it can
just use the appropriate pypi provides/requires. If the macro template
enables the requires generator, it won't even need to specify requires
at all, as they'll be generated from the wheel data anyway.
