SVN rev 220156 on 2011-03-30 12:35:39Z by jhb
Clamp the initial advertised receive window when responding to a SYN/ACK
to the maximum allowed window. Growing the window too large would cause
an underflow in the calculations in tcp_output() to decide if a window
update should be sent which would prevent the persist timer from being
started if data was pending and the other end of the connection advertised
an initial window size of 0.
