  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:
   * 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 addresses to IP_MULTICAST_IF
     which are then interpreted as interface indexes) is now deprecated.
   * A patch for the 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.
