score: SMP initialization and shutdown changes
Rename _SMP_Request_other_cores_to_perform_first_context_switch() into _SMP_Request_start_multitasking() since this requests now a multitasking start on all configured and available processors. The name corresponds _Thread_Start_multitasking() and _SMP_Start_multitasking_on_secondary_processor() actions issued in response to this request. Move in source file to right place. Rename PER_CPU_STATE_READY_TO_BEGIN_MULTITASKING into PER_CPU_STATE_READY_TO_START_MULTITASKING. Rename PER_CPU_STATE_BEGIN_MULTITASKING into PER_CPU_STATE_REQUEST_START_MULTITASKING. Rename _SMP_Request_other_cores_to_shutdown() into _SMP_Request_shutdown(). Add a per-CPU state lock to protect all changes. This was necessary to offer a controlled shutdown of the system (atomic read/writes alone are not sufficient for this kind of synchronization). Add documentation for Per_CPU_State. Delete debug output. New tests smptests/smpfatal01 and smptests/smpfatal02.
