Assorted bridge+ipfw+dummynet fixes.  The general goal of this set
of patches is to reduce the number of places where shared mbuf
clusters are modified.

In detail:
ip_fw.c:
    modified the ip_fw_chk interface (so that it does not consume
    the buffer unless strictly necessary).

ip_input.c, ip_output.c, bridge.c:
    reflect above changes.

if_ethersubr.c:
    avoid dereferencing pointers to an mbuf chain after it has been
    freed. Also fix some bugs when interfaces are not part of
    a bridging cluster.

ip_dummynet.[ch]
    largely simplified the WF2Q+ implementation removing a redundant
    data structrure.

bridge.[ch]
    fix the forwarding loop to avoid modifying the packet when
    possible.
