------------------------------+-----------------------------
 At some point during system initialization the idle threads are created.
 Afterwards the boot processor basically executes within the context of an
 idle thread with thread dispatching disabled. On some architectures, the
 thread-local storage state must be applied to processor registers. Add a
 new CPU port function to do this: `_CPU_Use_thread_local_storage(
 Context_Control *executing )`.
