pif: Pass originating pif to tap handler functions

Browse source 
For now, packets passed to the various *_tap_handler() functions always
come from the single "tap" interface.  We want to allow the possibility to
broaden that in future.  As preparation for that, have the code in tap.c
pass the pif id of the originating interface to each of those handler
functions.
