s-taasde.adb (Timer_Queue): Don't use a build-in-place function call to initialize the Timer_Queue.

	* s-taasde.adb (Timer_Queue): Don't use a
	build-in-place function call to initialize the Timer_Queue.
	* s-traent.adb, s-traent.ads, s-traent-vms.adb, s-traent-vms.ads:
	Turn off polling in these units, because otherwise we get
	elaboration circularities with Ada.Exceptions when the -gnatP
	switch is used.
	* s-tassta.adb (Create_Task): Make sure independent tasks
	are created with Parent = Environment_Task. This was not true,
	for example, in s-interr.adb, when Interrupt_Manager does "new
	Server_Task"; the Server_Task had Parent = Interrupt_Manager,
	which is wrong because the master is determined by the access
	type, which is at library level.
	* s-tasuti.adb (Make_Independent): Avoid setting Parent; it is
	now set correctly by Create_Task.
	(Make_Passive): Remove the workaround for the race condition in
	Make_Independent.
	* frontend.adb (Frontend): Revert to previous method of detecting
	temporary configuration pragma files, recognizing such files by
	".tmp" in the name. This is more general than detecting pragmas
	Source_File_Name_Project, because it allows any tool to use
	this naming convention, no matter the content of the file.
	* gnat_ugn.texi: Document this naming convention.
