Note: The CVS repository was tagged with NETHACK_PRE_MEXTRA
prior to application of this patch to allow easy withdrawal if necessary.
Adds a new mextra structure type that has a set
of pointers to various types of monster structures
including:
mname, egd, epri, eshk, emin, edog
Replaces the mextra bits in the monst structure
with a single pointer called mtmp->mextra of type
(struct mextra *).
The pointer can be null if there are no additional
structures attached. The mextra structure is not
adjacent to the monst structure.
Reduces the in-memory footprint of the monst that
has no other structures attached, at the cost
of adding 6 extra long ints per monster to
the save file
The new mextra structure has the mextra fields
independent of each other, not overlapping as was
the case with previous NetHack versions.
This patch doesn't do anything to capitalize on
that difference however.
Consolidates vault.h, epri.h, eshk.h, emin.h and edog.h
into mextra.h
Adds a macro for checking for whether a monster has
a name:
has_name(monst)
This fixes the magic trap panic
expels() -> spoteffects() -> dotrap() ->
domagictrap() -> tamedog()
because the monst no longer varies in size so no
replacement is required.

[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.
