copperwater 4b7f34f5f8 Refactor mongets to return the object it creates ...

The impetus for this was to avoid ugly constructions such as the one
below (none of which currently appear in vanilla NetHack):

mongets(mtmp, LONG_SWORD);
struct obj* sword = m_carrying(mtmp, LONG_SWORD);
if (sword)
  /* do thing to sword */

Most cases where mongets is used discard the returned value (which used
to be the created object's spe); the only places that do use it are the
series of statements that give various human monsters armor and prevent
them from getting too much armor. These statements included hardcoded
constants representing the base AC of the armor, which would have caused
discrepancies if armor's base AC were ever changed.

With mongets now returning a pointer to the created object, it can just
be passed into ARM_BONUS instead, which covers both the base AC and the
enchantment. (It will also cover erosion, if anyone ever decides that
armor should rarely generate as pre-eroded).

The overall algorithm is not changed by this; human monsters should
receive armor with the same probabilities as before.
