Renamed _SMP_Broadcast_message and _SMP_Send_message_cpu_set to _SMP_Send_message_broadcast and _SMP_Send_message_multicast and changed the broadcast type to unsigned long. Broadcast no longer uses multicast.
Now supports arbitrarily sized cpu sets. Dropped use of function ids in smp cache manager. Prevent thread dispatch in smp cache manager to avoid same core trying to take the same lock twice. Use TAS-lock instead of ticket lock. If we fail to take the lock, and interrupts are disabled, another core might be waiting for us to service a smp message. So each time we fail we also look at the per cpu message bitmask to see if there is cache smp message for us. Added warning about using the smp cache manager from interrupt context. No extra function for instruction cache invalidation. If RTEMS_SMP is defined and the BSP has defined CPU_CACHE_NO_INSTRUCTION_CACHE_SNOOPING then the normal instruction cache invalidation operation will invalidate all processors instruction cache. This removes the need to patch _CPU_ISR_install_raw_handler If the state is not up, all cache operations will be local. It is up to each core to flush their caches if needed before starting to service interrupts or tasks. Added an extra error message to differentiate between the main processor not having data cache snooping enabled and a secondary processor not having data cache snooping enabled.
