	rtems/src/taskdelete.c, rtems/src/timerserver.c,
	score/src/threadclose.c, score/src/threadcreateidle.c,
	score/src/threadinitialize.c: Switch task create and delete
	operations to using API Allocator Mutex. This moves almost all uses
	of the RTEMS Workspace from dispatching disabled to mutex protected
	which should improve deterministic behavior. The implementation was
	carefully done to allow task create and delete extensions to invoke
	more services. In particular, a task delete extension should be able
	to do mutex and file operations.
