Sebastian Huber 31036f1dc8 score: Use priority inheritance for thread join
Threads may join the thread termination of another thread using the
pthread_join() or rtems_task_delete() directives.  The thread cancel operation
used a special case priority boosting mechanism implemented by
_Thread_Raise_real_priority().  The problem was that this approach

* is not transitive,

* does not account for priority adjustments of the calling task
  while waiting for the join,

* does not support clustered scheduling, and

* does not detect deadlocks.

All these problems are fixed by using a priority inheritance thread queue for
the join operation.

Close #4679.
