Output TCP snd_cwnd (on platforms supporting it) in normal output.
We were computing and printing this in JSON output mode anyway; this
change just exposes this quantity in a human-friendly manner (better
than the first attempt at this) when doing normal output.
Resolves Issue 99 (Additional TCP_INFO items).
