	* nios2-context-initialize.c, nios2-context-switch.S,
	nios2-fatal-halt.c, nios2-initialize-vectors.c, nios2-initialize.c,
	nios2-isr-get-level.c, nios2-isr-install-raw-handler.c,
	nios2-isr-install-vector.c, nios2-isr-is-in-progress.c,
	nios2-isr-set-level.c, nios2-thread-dispatch-disabled.c,
	rtems/score/nios2-utility.h: New files.
	* Makefile.am, preinstall.am: Reflect changes above.
	* irq.c: Update due to API changes.
	* rtems/score/cpu.h: New functions _CPU_Initialize_vectors(),
