Changeset: http://git.rtems.org/rtems/commit/?id=4d1f5008dbce6567e9501de8b7623b245c9f8283

score: Rename _Scheduler_Update()
Rename _Scheduler_Update() to _Scheduler_Update_priority(). Add
parameter for the new thread priority to avoid direct usage of
Thread_Control::current_priority in the scheduler operation.
