rS334804: This commit brings in a new refactored TCP stack called Rack.
Summary

This is the first cut at placing the rack that Netflix is using into
the FreeBSD tree. It includes all the ground work as well for
BBR (which is the follow on module still being developed jointly
with google).

There are a few places in here where I added
#ifdef NETFLIX_xxxx
where xxx is STATS (which lstewart plans to upstream eventually)

 CWV (A attempt of congestion window validation)
TCPOUDP (A implementation that runs TCP over UDP that we are working on)

Most all of these will be upstreamed or we will at least off them upstream eventually.

Test Plan

Build this critter and run iperf and other fun with the default set to rack
making sure the connections work like they do at NF.
