  Modified files:
    sys/net              if_ethersubr.c 
    sys/net/bridge       if_bridge.c 
  Don't let ether_input() to do the bridging work, i.e. change input iface,
  since it breaks following things:
  o  IFF_MONITOR support.
  o  Assumption that ether_input() is called with input iface's serializer
  o  Per interface input packets and bytes statistics.
  Let the bridge(4) handle the input iface change, which is centralized
  at the end of bridge_input() after leaving bridge(4) iface's serializer.
  We call ifnet.if_input() when handling iface change, instead of skipping
  the "upper" half of ifnet.if_input() as we did originally; the assumption
  that "upper" half of ifnet.if_input() does nothing according to input iface
  does not sounds good.  M_PROTO1 mbuf flag is used to prevent infinite loop;
  we may need to create a meaningful alias macro for it.
  Other changes:
  - Delay bridge_lookup_member_if() call until it is really necessary.
  - Update ipackets for bridge(4) iface, if mcast/bcast packet is received
    and is going to be delivered to bridge(4) iface.
  - Use IF_LLADDR() macro to get bridge(4) iface's MAC address.
  - Nuke never reached code.
  - Minor style changes.
