Hi,

I went back and reworked the code mainly to fix up the broken fast
retransmit.  I also took a stab at carving off the congestion control related
code into a set of plugable functions accessed via a struct of fnpointers.

It should make tweaking the congestion control code a tiny bit easier.

The math in the bandwidth estimation algorithm is still a bit iffy,
but this TCP variant is aimed at high BDP links, so it's probably ok.
