score: Add CPU_Exception_frame

Browse Source 
Add CPU port type CPU_Exception_frame and function
_CPU_Exception_frame_print().

The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh,
sparc64, and v850 use an empty default implementation of
_CPU_Exception_frame_print().

Add rtems_exception_frame and rtems_exception_frame_print().

Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions.  Use rtems_fatal()
with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc,
and sparc for unexpected exceptions.

Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the
BSP_PRINT_EXCEPTION_CONTEXT define used in the default
bsp_fatal_extension().

Add test sptests/spfatal26.
