[Ada] Clean up wrt abort notation

[Arnaud Charlet <charlet at adacore dot com>]

Tested on i686-linux, committed on HEAD

The procedures Defer/Undefer_Abortion should not be used within the GNAT
run-time, as more efficient counter parts exist (e.g. Defer_Abort), so move
these procedures to the body so that they can no longer be called within the
run-time.
Also, using the word 'abortion', although technically correct is something
we want to avoid by using e.g. 'abort' instead.

	* s-tataat.adb, a-tasatt.adb:
	Replace calls to Defer/Undefer_Abortion by Defer/Undefer_Abort.

	* s-tasini.ads, s-tasini.adb (Defer_Abortion, Undefer_Abortion): Moved
	these procedures to body, and renamed Abort_Defer, Abort_Undefer.
	(Get_Exc_Stack_Addr, Set_Exc_Stack_Addr): Removed, no
	longer used.
