	PR 1635/cpukit
	* sapi/src/exinit.c, score/Makefile.am, score/preinstall.am,
	score/include/rtems/score/bitfield.h,
	score/include/rtems/score/priority.h,
	score/include/rtems/score/thread.h,
	score/inline/rtems/score/priority.inl,
	score/inline/rtems/score/thread.inl,
	score/src/threadchangepriority.c, score/src/threadclearstate.c,
	score/src/threadready.c, score/src/threadresume.c,
	score/src/threadsetpriority.c, score/src/threadsetstate.c,
	score/src/threadsettransient.c, score/src/threadsuspend.c:
	Refactoring of priority handling, to isolate the bitmap
	implementation of priorities in the supercore so that priority
	management is a little more modular. This change is in anticipation
	of scheduler implementations that can select how they manage tracking
	priority levels / finding the highest priority ready task. Note that
	most of the changes here are simple renaming, to clarify the use of
	the bitmap-based priority management.
	* score/include/rtems/score/prioritybitmap.h,
	score/inline/rtems/score/prioritybitmap.inl: New files.
