* cpu.c, avr/interrupt.h, avr/power.h, rtems/score/cpu.h:
	Use "__asm__" instead of "asm" for improved c99-compliance.

PR 1635/cpukit
	* rtems/score/cpu.h, rtems/score/types.h: 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.
