kernel - MPSAFE the protocol drain routines
* The ip fragment drain was not MPSAFE at all. Use a token to protect
the ipq[] queues.
* The tcp reassembly code was only partially MPSAFE due to being
per-cpu. Finish it up. Use atomic ops for the tcp_reass_qsize
global.
* Add port assertions in the TCP input and output paths. If we
are not in the correct thread we panic, period.
* Code cleanup.
