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.
