[confirmed: moveloop -> deferred_goto -> goto_level ->
losedogs -> mon_arrive -> rloc -> impossible]
This patch:
- causes rloc() to return TRUE if successful,
or FALSE if it wasn't.
- adds code to mon_arrive() in dog.c to deal with
the failed rloc()
- allows the x,y parameters to mkcorpstat() to
be 0,0 in order to trigger random placement of the
corpse on the level
- if you define DEBUG_MIGRATING_MONS when you build cmd.c
then you'll have a debug-mode command #migratemons to
store the number of random monsters that you specify
on the migrating monsters chain.

Applying at the water location next to you was easy. But
applying it at your own location (triggering BY_YOU) could
end up placing the figurine at the far side of the level if
there was lots of water.
Correcting that required the ability to pass a flag from
make_familiar to makemon() telling it to not rule out
water locations as good positions. The flag had to
be passed on down to goodpos() and enexto().
The bulk of this patch is just adding an additional
argument to goodpos() in all of the callers.
