  Modified files:
    sys/netinet          udp_usrreq.c 
  Log:
  Deal with multicast packets in a manner similar to Solaris, RFC 3376, and
  draft-ietf-magma-msf-api-05.txt.   Multicast packets are not sent to
  multicast-unaware sockets or to sockets not bound to the interface the
  packet came in on.
  
  The sysctl net.inet.udp.strict_mcast_mship enables the new requirements
  by default.  Original operation may be recovered by setting the sysctl to 0.
  
  There is a relatively minor scaling issue with the per-PCB membership
  array scan, which is linear.  It is not a show stopper though.
