* _Thread_Yield_processor
*
* This kernel routine will remove the running THREAD from the ready chain
* and place it immediatly at the rear of this chain. Reset timeslice
* and yield the processor functions both use this routine, therefore if
* reset is true and this is the only thread on the chain then the
* timeslice counter is reset. The heir THREAD will be updated if the
* running is also the currently the heir.
*
* Input parameters: NONE
*
* Output parameters: NONE
*
* INTERRUPT LATENCY:
* ready chain
* select heir
