* spsize/size.c: Add next step in SMP support. This adds an allocated
array of the Per_CPU structures to support multiple cpus vs a single
instance of the structure which is still used if SMP support is
disabled. Configuration support is also added to explicitly enable or
disable SMP. But SMP can only be enabled for the CPUs which will
support it initially -- SPARC and i386. With the stub BSP support, a
BSP can be run as a single core SMP system from an RTEMS data
structure standpoint.
