andre b824892b57 Increase the initial CWND to 10 segments as defined in IETF TCPM ...

draft-ietf-tcpm-initcwnd-05. It explains why the increased initial
window improves the overall performance of many web services without
risking congestion collapse.

As long as it remains a draft it is placed under a sysctl marking it
as experimental:
 net.inet.tcp.experimental.initcwnd10 = 1
When it becomes an official RFC soon the sysctl will be changed to
the RFC number and moved to net.inet.tcp.

This implementation differs from the RFC draft in that it is a bit
more conservative in the case of packet loss on SYN or SYN|ACK because
we haven't reduced the default RTO to 1 second yet.  Also the restart
window isn't yet increased as allowed.  Both will be adjusted with
upcoming changes.

Is is enabled by default.  In Linux it is enabled since kernel 3.0.
