* sapi/include/confdefs.h, sapi/include/rtems/config.h,
sapi/include/rtems/init.h, sapi/src/exinit.c,
score/include/rtems/system.h, score/src/isr.c: Move
interrupt_stack_size field from CPU Table to Configuration Table.
Eliminate CPU Table from all ports. Delete references to CPU Table in
all forms.
