This is something I would love to see: UDP refactored so that it gets
its hash tables/lookup code more and more looking like what we have in
inet_hashtables (struct inet_hashinfo, etc) so that udp_diag would just
fit in the inet_diag infrastructure, like dccp, that is in some aspects
like TCP and in others like UDP and already uses this infrastructure.
