[TCP]: TCP Illinois congestion control (rev3)

This is an implementation of TCP Illinois invented by Shao Liu
at University of Illinois. It is a another variant of Reno which adapts
the alpha and beta parameters based on RTT. The basic idea is to increase
window less rapidly as delay approaches the maximum. See the papers
and talks to get a more complete description.

+        TCP-Illinois is a sender-side modificatio of TCP Reno for
+        high speed long delay links. It uses round-trip-time to
+        adjust the alpha and beta parameters to achieve a higher average
+        throughput and maintain fairness.
