Summary:

- We disallow multicast operations on divert sockets.  It really doesn't make
  semantic sense to allow this, since typically you would set multicast
  parameters on multicast end points.

  NOTE: As a part of this change, we actually dis-allow multicast options on
  any socket that IS a divert socket OR IS NOT a SOCK_RAW or SOCK_DGRAM family

- We check to see if there are any socket options that have been specified on
  the socket, and if there was (which is very un-common and also probably
  doesnt make sense to support) we duplicate the mbuf carrying the options.

- We then drop the INP/INFO locks over the call to ip_output().  It should be
  noted that since we no longer support multicast operations on divert sockets
  and we have duplicated any socket options, we no longer need the reference
  to the pcb to be coherent.

- Finally, we replaced the call to ip_input() to use netisr queuing.  This
  should remove the recursive entry into the IP stack from divert.

(The ip_output.c changes come from in_mcast.c in head.)
