	PR 1743/cpu
	* sapi/include/confdefs.h, score/Makefile.am, score/preinstall.am: Add

	Priority Scheduler. This scheduler serves both as an example and as a
	lighter weight implementation for smaller systems.
	* score/include/rtems/score/schedulersimple.h,
	score/inline/rtems/score/schedulersimple.inl,
	score/src/schedulersimple.c, score/src/schedulersimpleblock.c,
	score/src/schedulersimpleenqueue.c,
	score/src/schedulersimpleenqueuefirst.c,
	score/src/schedulersimpleextract.c,
	score/src/schedulersimplereadyqueueenqueue.c,
	score/src/schedulersimplereadyqueueenqueuefirst.c,
	score/src/schedulersimpleschedule.c,
	score/src/schedulersimpleunblock.c, score/src/schedulersimpleyield.c:
	New files.
