[TCP]: Add TCP BIC congestion control module.
TCP BIC congestion control reworked to use the new congestion control infrastructure. This version is more up to date than the BIC code in 2.6.12; it incorporates enhancements from BICTCP 1.1, to handle low latency links.

+ BIC-TCP is a sender-side only change that ensures a linear RTT
+ fairness under large windows while offering both scalability and
+ bounded TCP-friendliness. The protocol combines two schemes
+ called additive increase and binary search increase. When the
+ congestion window is large, additive increase with a large
+ increment ensures linear RTT fairness as well as good
+ scalability. Under small congestion windows, binary search
+ increase provides TCP friendliness.
