Richard Scheffenegger 0e5e35e322 Extend netstat to display TCP stack and detailed congestion state 
Adding the "-c" option used to show detailed per-connection
congestion control state for TCP sessions.

This is one summary patch, which adds the relevant variables into
xtcpcb. As previous "spare" space is used, these changes are ABI
compatible.
