defconfig: Enable Advanced TCP Congestion Control

Enable Westwood+, Hamilton-TCP, Vegas & Veno.
Also, set H-TCP as the default. Prime testing conditions for Mobile
Networks show consistently good results from H-TCP.

Research from the Academy of Business in Dąbrowa Górnicza, Poland
suggests that 3G connections deliver IP parameters similar to wired
connections. The study also suggests that further testing be done
on congestion control algorithms designed for fast networks
because of this (YeAH, Highspeed, Hamilton). Similar can likely be
said for even stronger networks (such as HSDPA & LTE). And while I
have yet to find any follow-up report by the same author, testing
with H-TCP has improved throughput on mobile connections
consistently.
