        sys/sys/param.h: bump revision

Port over the TCP_INFO socket option from FreeBSD, originally from
the Linux 2.6 TCP API.  This permits the caller to query certain information
about a TCP connection, and is used by pkgsrc's net/iperf3 test program
if available.

This extends struct tcbcb with three fields to count retransmits,
out-of-sequence receives and zero window announcements, and will
therefore warrant a kernel revision bump (done separately).

Change the new counter variables in struct tcpcb to uint32_t, as
per christos' comments.
