a-fihema.ads, [...] (Finalization_Collection): Avoid heap allocation for Objects component.

	* a-fihema.ads, a-fihema.adb (Finalization_Collection): Avoid heap
	allocation for Objects component. This simplifies the code somewhat. It
	is also a little more efficient in the not-so-unusual case where there
	are no controlled objects allocated.
	Make Finalization_Started flag atomic.
	(Finalize): Avoid unnecessary detachment of items from the list.
	(pcol): Minor cleanup.
