Sebastian Huber 7336be9d78 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.
