Just RH0 related code of course. Preserving compatibility with RFC2292 in
general is must be.

And we must preserve it as well. You should be careful not to break whole
world of course by removing blindly all strings that contain "rth" :).
All inet6_rthdr_*() functions must exists (from both old and new API),
but there is no point to handle RH0 in these. For now where we don't
support type 2 routing headers these functions can be simple "return
something that shows we don't support any routing header type".
