* rtems/score/cpu.h: Mark _CPU_Context_restore() as noreturn so the
	compiler will not generate code thinking it returns.

* Makefile.am: added AVR specific Header files to score/cpu/avr/avr.
	These are from avr-libc 1.6 and assumed to exist by AVR applications.
	* preinstall.am: Regenerated.

* cpu.c, cpu_asm.S, rtems/score/cpu.h: Context switch now works well
	enough to run ticker to completion with the simulator clock idle
	task. But if you comment out the printk's in _CPU_Context_Initialize,
	it hangs. This remains to be investigated.

*cpu_asm.S: implemented _CPU_Context_Restore by adding tags to
	restore section of context switch.
	Fixed bug in _CPU_Context_Switch. The wrong registers were being
	used for pointer to running task Context_Control struct.

* cpu.c: Implemented _CPU_Context_Initialize as a C function instead
	of a macro.  It works with limited functionality.  Implemented
	_CPU_Thread_Idle_body to use sleep instruction.
	* Makefile.am: Changed cpu_asm.c -> cpu_asm.S
	* cpu_asm.S: renamed from cpu_asm.c and implemented functions is asm
	* rtems/asm.h: Appended "macros.inc" to the end of "asm.h"
	* rtems/score/cpu.h:
	  + Included "avr/io.h".
	  + Added use 16 bit object definition.
	  + Modified Context_Control struct to relect the registers
	    that need to be saved.
	  + Implemented _CPU_ISR_Disable, _CPU_ISR_Enable, and _CPU_ISR_Flash.
	    Added function definitions for _CPU_Context_Initialize and
	    _CPU_Push.

* cpu.h: corrected the registers in Context_Control and
	in CPU_Interrupt_frame to correspond to the saved frame in cpu_asm.S
   	Also switched on CPU_ISR_PASSES_FRAME_POINTER.
 	* cpu_asm.S: Moved the restore part of _CPU_Context_switch for
	easier reading.  Fixed _CPU_Context_restore, it now moves the
	argument and branches to a label in _CPU_Context_switch.  Removed
	unnecessary saves of registers in context switch and irq handling.
	Rewrote irq code to call the C helper.  Added some documentation
	* irq.c: New file derived from c4x and nios2.

PR 1385/cpukit
	* cpu_asm.S: When the type rtems_boolean was switched to the C99 bool,
	the size changed from 4 bytes to 1 byte. The interrupt dispatching
	code accesses two boolean variables for scheduling purposes and the
	assembly implementations of this code did not get updated.
