Modified Files:
        src/sys/net: if.c pktqueue.c pktqueue.h

Log Message:
Re-factor how pktq_barrier() is issued by if_detach().

Rather than excplicitly referencing ip_pktq and ip6_pktq in if_detach(),
instead add all pktqueues to a global list.  This list is then used in
the new pktq_ifdetach() function to issue a barrier on all pktqueues.

Note that the performance of this list is not critical; it will seldom
be accessed (then pktqueues are created/destroyed and when network
interfaces are detached), and so a simple synchronization strategy using
a rwlock is sufficient.
