 score: Introduce map priority scheduler operation

 Introduce map/unmap priority scheduler operations to map thread priority
 values from/to the user domain to/from the scheduler domain.  Use the
 map priority operation to validate the thread priority.  The EDF
 schedulers use this new operation to distinguish between normal
 priorities and priorities obtain through a job release.

 Update #2173.
 Update #2556.
