Rename in rtems_smp_get_processor_count(). Always provide <rtems/score/smp.h> and <rtems/rtems/smp.h>. Add _SMP_Get_processor_count(). This function will be a compile time constant defined to be one on uni-processor configurations. This allows iterations over all processors without overhead on uni-processor configurations.
