        src/share/man/man4: tcp.4
        src/sys/netinet: tcp.h tcp_input.c tcp_output.c tcp_subr.c tcp_usrreq.c
            tcp_var.h

Log Message:
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).
