	* a-rttiev.ads, a-rttiev.adb:
	This is a significant redesign primarily for the sake of automatic
	timer task termination but also to fix a design flaw.
	Therefore we are now using an RTS lock, instead of a protected
	object, to provide mutual exclusion to the queue of pending events
	and the type Timing_Event is no longer a protected type.
