   Log:
   Import rewrite of IPv4 socket multicast layer to support source-specific
   and protocol-independent host mode multicast. The code is written to
   accomodate IPv6, IGMPv3 and MLDv2 with only a little additional work.
 
   This change only pertains to FreeBSD's use as a multicast end-station and
   does not concern multicast routing; for an IGMPv3/MLDv2 router
   implementation, consider the XORP project.
 
   The work is based on Wilbert de Graaf's IGMPv3 code drop for FreeBSD 4.6,
   which is available at: http://www.kloosterhof.com/wilbert/igmpv3.html
 
   Summary
    * IPv4 multicast socket processing is now moved out of ip_output.c
      into a new module, in_mcast.c.
    * The in_mcast.c module implements the IPv4 legacy any-source API in
      terms of the protocol-independent source-specific API.
    * Source filters are lazy allocated as the common case does not use them.
      They are part of per inpcb state and are covered by the inpcb lock.
    * struct ip_mreqn is now supported to allow applications to specify
      multicast joins by interface index in the legacy IPv4 any-source API.
    * In UDP, an incoming multicast datagram only requires that the source
      port matches the 4-tuple if the socket was already bound by source port.
      An unbound socket SHOULD be able to receive multicasts sent from an
      ephemeral source port.
    * The UDP socket multicast filter mode defaults to exclusive, that is,
      sources present in the per-socket list will be blocked from delivery.
    * The RFC 3678 userland functions have been added to libc: setsourcefilter,
      getsourcefilter, setipv4sourcefilter, getipv4sourcefilter.
    * Definitions for IGMPv3 are merged but not yet used.
    * struct sockaddr_storage is now referenced from <netinet/in.h>. It
      is therefore defined there if not already declared in the same way
      as for the C99 types.
    * The RFC 1724 hack (specify 0.0.0.0/8 addresses to IP_MULTICAST_IF
      which are then interpreted as interface indexes) is now deprecated.
    * A patch for the Rhyolite.com routed in the FreeBSD base system
      is available in the -net archives. This only affects individuals
      running RIPv1 or RIPv2 via point-to-point and/or unnumbered interfaces.
    * Make IPv6 detach path similar to IPv4's in code flow; functionally same.
    * Bump __FreeBSD_version to 700048; see UPDATING.
