  Modified files:
    sys/netinet          tcp_input.c udp_usrreq.c 
  Log:
  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.
