csgr 83e27dbadf Add net.inet.tcp.blackhole and net.inet.udp.blackhole
sysctl knobs.

With these knobs on, refused connection attempts are dropped
without sending a RST, or Port unreachable in the UDP case.
In the TCP case, sending of RST is inhibited iff the incoming
segment was a SYN.

Docs and rc.conf settings to follow.
