* Generic Timeout Functions.
*
* Interface:
*
* General:
* boolean start_timer(long timeout,short kind,short func_index,
* anything *arg)
* Start a timer of kind 'kind' that will expire at time
* svm.moves+'timeout'. Call the function at 'func_index'
* in the timeout table using argument 'arg'. Return TRUE if
* a timer was started. This places the timer on a list ordered
* "sooner" to "later". If an object, increment the object's
* timer count.
*
* long stop_timer(short func_index, anything *arg)
* Stop a timer specified by the (func_index, arg) pair. This
* assumes that such a pair is unique. Return the time the
* timer would have gone off. If no timer is found, return 0.
* If an object, decrement the object's timer count.
*
* long peek_timer(short func_index, anything *arg)
* Return time specified timer will go off (0 if no such timer).
*
* void run_timers(void)
* Call timers that have timed out.
*
* Save/Restore:
* void save_timers(NHFILE *, int range)
* Save all timers of range 'range'. Range is either global
* or local. Global timers follow game play, local timers
* are saved with a level. Object and monster timers are
* saved using their respective ids instead of pointers.
*
* void restore_timers(NHFILE *, int range, long adjust)
* Restore timers of range 'range'. If from a ghost pile,
* adjust the timeout by 'adjust'. The object and monster
* ids are not restored until later.
*
* void relink_timers(boolean ghostly)
* Relink all object and monster timers that had been saved
* using their object's or monster's id number.
*
* Object Specific:
* void obj_move_timers(struct obj *src, struct obj *dest)
* Reassign all timers from src to dest.
*
* void obj_split_timers(struct obj *src, struct obj *dest)
* Duplicate all timers assigned to src and attach them to dest.
*
* void obj_stop_timers(struct obj *obj)
* Stop all timers attached to obj.
*
* boolean obj_has_timer(struct obj *object, short timer_type)
* Check whether object has a timer of type timer_type.
