Xtables cleanup patches

[Jan Engelhardt <jengelh@medozas.de>]

I am posting here already the next round of pullable patches
(that I originally wanted to get in _much_ faster) for review.

This block is mostly cleanups, simplifications. It might be worth
testing these together with the previous set if there are concerns
about speed.
