Make player fully aware of the given mimic.
When a player becomes aware of a mimic, we update the monster memory and delete the "fake item" that the monster was mimicking.

Decreases a monster's hit points by dam and handle monster death.
Hack – we "delay" fear messages by passing around a "fear" flag.
We announce monster death (using an optional "death message" (note) if given, and a otherwise a generic killed/destroyed message).
Returns true if the monster has been killed (and deleted).
TODO: Consider decreasing monster experience over time, say, by using "(m_exp * m_lev * (m_lev)) / (p_lev * (m_lev + n_killed))" instead of simply "(m_exp * m_lev) / (p_lev)", to make the first monster worth more than subsequent monsters. This would also need to induce changes in the monster recall code. XXX XXX XXX

Handles the "death" of a monster.
Disperses treasures carried by the monster centered at the monster location. Note that objects dropped may disappear in crowded rooms.
Checks for "Quest" completion when a quest monster is killed.
Note that only the player can induce "monster_death()" on Uniques. Thus (for now) all Quest monsters should be Uniques.
If stats is true, then we skip updating the monster memory. This is used by stats-generation code, for efficiency.

This function updates the monster record of the given monster.
This involves extracting the distance to the player (if requested), and then checking for visibility (natural, infravision, see-invis, telepathy), updating the monster visibility flag, redrawing (or erasing) the monster when its visibility changes, and taking note of any interesting monster flags (cold-blooded, invisible, etc).
Note the new "mflag" field which encodes several monster state flags, including "view" for when the monster is currently in line of sight, and "mark" for when the monster is currently visible via detection.
The only monster fields that are changed here are "cdis" (the distance from the player), "ml" (visible to the player), and "mflag" (to maintain the "MFLAG_VIEW" flag).
Note the special "update_monsters()" function which can be used to call this function once for every monster.
Note the "full" flag which requests that the "cdis" field be updated; this is only needed when the monster (or the player) has moved.
Every time a monster moves, we must call this function for that monster, and update the distance, and the visibility. Every time the player moves, we must call this function for every monster, and update the distance, and the visibility. Whenever the player "state" changes in certain ways ("blindness", "infravision", "telepathy", and "see invisible"), we must call this function for every monster, and update the visibility.
Routines that change the "illumination" of a grid must also call this function for any monster in that grid, since the "visibility" of some monsters may be based on the illumination of their grid.
Note that this function is called once per monster every time the player moves. When the player is running, this function is one of the primary bottlenecks, along with "update_view()" and the "process_monsters()" code, so efficiency is important.
Note the optimized "inline" version of the "distance()" function.
A monster is "visible" to the player if (1) it has been detected by the player, (2) it is close to the player and the player has telepathy, or (3) it is close to the player, and in line of sight of the player, and it is "illuminated" by some combination of infravision, torch light, or permanent light (invisible monsters are only affected by "light" if the player can see invisible).
Monsters which are not on the current panel may be "visible" to the player, and their descriptions will include an "offscreen" reference. Currently, offscreen monsters cannot be targeted or viewed directly, but old targets will remain set. XXX XXX
The player can choose to be disturbed by several things, including "OPT(player, disturb_near)" (monster which is "easily" viewable moves in some way). Note that "moves" includes "appears" and "disappears".
