Introduce new link-layer PFIL hook V_link_pfil_hook.
Merge ether_ipfw_chk() and part of bridge_pfil() into
unified ipfw_check_frame() function called by PFIL.
This change was suggested by rwatson? @ DevSummit.

Remove ipfw headers from ether/bridge code since they are unneeded now.

Note this thange introduce some (temporary) performance penalty since
PFIL read lock has to be acquired for every link-level packet.
