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.
