Bring together the three performance improvements suggested.
  1) RCU for ip_tables entries
  2) mod_timer_noact for conntrack timer
  3) eliminate tcp_lock

I took the patches for 2 & 3 and made them build and basically work.

This patch set is against Patrick's netfilter next tree since
it is where it should end up.
