	Significant clean up on Scheduler Plugin Interface. Names were
	shortened. Missing operations added. Many scheduler files had
	unneeded includes removed. Made pointer to scheduler information in
	Thread_Control and Scheduler_Control a void * pointer because the
	thread and scheduler wrapper should be unaware of scheduler types AND
	this is broken for user provided schedulers.
