/*
 * Build a string describing a monster in some way.
 *
 * We can correctly describe monsters based on their visibility.
 * We can force all monsters to be treated as visible or invisible.
 * We can build nominatives, objectives, possessives, or reflexives.
 * We can selectively pronominalize hidden, visible, or all monsters.
 * We can use definite or indefinite descriptions for hidden monsters.
 * We can use definite or indefinite descriptions for visible monsters.
 *
 * Pronominalization involves the gender whenever possible and allowed,
 * so that by cleverly requesting pronominalization / visibility, you
 * can get messages like "You hit someone.  She screams in agony!".
 *
 * Reflexives are acquired by requesting Objective plus Possessive.
 *
 * If no m_ptr arg is given (?), the monster is assumed to be hidden,
 * unless the "Assume Visible" mode is requested.
 *
 * If no r_ptr arg is given, it is extracted from m_ptr and r_info
 * If neither m_ptr nor r_ptr is given, the monster is assumed to
 * be neuter, singular, and hidden (unless "Assume Visible" is set),
 * in which case you may be in trouble... :-)
 *
 * I am assuming that no monster name is more than 70 characters long,
 * so that "char desc[80];" is sufficiently large for any result.
 *
 * Mode Flags:
 *   0x01 --> Objective (or Reflexive)
 *   0x02 --> Possessive (or Reflexive)
 *   0x04 --> Use indefinites for hidden monsters ("something")
 *   0x08 --> Use indefinites for visible monsters ("a kobold")
 *   0x10 --> Pronominalize hidden monsters
 *   0x20 --> Pronominalize visible monsters
 *   0x40 --> Assume the monster is hidden
 *   0x80 --> Assume the monster is visible
 *
 * Useful Modes:
 *   0x00 --> Full nominative name ("the kobold") or "it"
 *   0x04 --> Full nominative name ("the kobold") or "something"
 *   0x80 --> Genocide resistance name ("the kobold")
 *   0x88 --> Killing name ("a kobold")
 *   0x22 --> Possessive, genderized if visable ("his") or "its"

/*
 * This function updates the monster record of the given monster
 *
 * This involves extracting the distance to the player, checking
 * for visibility (natural, infravision, see-invis, telepathy),
 * updating the monster visibility flag, redrawing or erasing the
 * monster when the visibility changes, and taking note of any
 * "visual" features of the monster (cold-blooded, invisible, etc).
 *
 * The only monster fields that are changed here are "cdis" (the
 * distance from the player), "los" (clearly visible to player),
 * and "ml" (visible to the player in any way).
 *
 * There are a few cases where the calling routine knows that the
 * distance from the player to the monster has not changed, and so
 * we have a special parameter "full" to request distance computation.
 * This lets many calls to this function run very quickly.
 *
 * Note that every time a monster moves, we must call this function
 * for that monster, and update distance.  Note that every time the
 * player moves, we must call this function for every monster, and
 * update distance.  Note that every time the player "state" changes
 * in certain ways (including "blindness", "infravision", "telepathy",
 * and "see invisible"), we must call this function for every monster.
 *
 * The routines that actually move the monsters call this routine
 * directly, and the ones that move the player, or notice changes
 * in the player state, call "update_monsters()".
 *
 * Routines that change the "illumination" of grids must also call
 * this function, 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, so it is important to optimize it for monsters which
 * are far away.  Note the optimization which skips monsters which
 * are far away and were completely invisible last turn.
 *
 * Note the optimized "inline" version of the "distance()" function.
 *
 * Note that only monsters on the current panel can be "visible",
 * and then only if they are (1) in line of sight and illuminated
 * by light or infravision, or (2) nearby and detected by telepathy.
 *
 * The player can choose to be disturbed by several things, including
 * "disturb_move" (monster which is viewable moves in some way), and
 * "disturb_near" (monster which is "easily" viewable moves in some
 * way).  Note that "moves" includes "appears" and "disappears".
 *
 * Note the new "xtra" field which encodes several state flags such
 * as "detected last turn", and "detected this turn", and "currently
 * in line of sight", all of which are used for visibility testing.

 * XXX XXX XXX Player Ghosts are such a hack, they have been completely

 * which will be extracted from a "bone" file, or replaced with a
 * "default" name if a real name is not available.  Each ghost will
 * appear exactly once and will not induce a special feeling.
 *
 * Possible methods:
 *   (s) 1 Skeleton
 *   (z) 1 Zombie
 *   (M) 1 Mummy
 *   (G) 1 Polterguiest, 1 Spirit, 1 Ghost, 1 Shadow, 1 Phantom
 *   (W) 1 Wraith
 *   (V) 1 Vampire, 1 Vampire Lord
 *   (L) 1 Lich
 *
 * Possible change: Lose 1 ghost, Add "Master Lich"
 *
 * Possible change: Lose 2 ghosts, Add "Wraith", Add "Master Lich"
 *
 * Possible change: Lose 4 ghosts, lose 1 vampire lord
 *
 * Note that ghosts should never sleep, should be very attentive, should
 * have maximal hitpoints, drop only good (or great) items, should be
 * cold blooded, evil, undead, immune to poison, sleep, confusion, fear.
 *
 * Base monsters:
 *   Skeleton
 *   Zombie
 *   Mummy
 *   Poltergeist
 *   Spirit
 *   Ghost
 *   Vampire
 *   Wraith
 *   Vampire Lord
 *   Shadow
 *   Phantom
 *   Lich
 *
 * This routine will simply extract ghost names from files, and
 * attempt to allocate a player ghost somewhere in the dungeon,
 * note that normal allocation may also attempt to place ghosts,
 * so we must work with some form of default names.
