fw: the gateway relay decides the same way the card does

relay() and permitted() were the same twenty lines twice: parse, work
out which end is the peer, consult the flow table, consult the rules,
log, count, remember.  Two copies that had already drifted -- relay
printed "(state)" and "(new)" under -d and permitted printed neither,
and the two spelled the drop reason differently -- and every fix since
has had to be made in both, which is how the copies drift further.

Now relay reads a packet, asks permitted, and writes it or does not.
The debug line permitted was missing is added rather than dropped, so
-d still distinguishes a packet the flow table let through from one the
rules did.

No new checks: the point is that nothing changes.  The gateway tests
already cover this path -- a connection crossing, one rule serving both
directions, a rule change killing a live flow -- and all 60 pass.
