99fc1d1d1b score: Rework EDF scheduler 
Use inline red-black tree insert.  Do not use shifting priorities since
this is not supported by the thread queues.  Due to the 32-bit
Priority_Control this currently limits the uptime to 49days with a 1ms
clock tick.

Update #2173.

7ec66e0890 score: Remove hidden deadline overrule for CBS 
Do what the user commands.  Maybe we should add a rtems_cbs_period()
that calls rtems_rate_monotonic_period() with the right parameter.

Update #2173.

77ff5599e0 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.

b8f76fa28e score: Delete unused _Scheduler_Priority_compare() 
By convention, thread priorities must be integers in RTEMS.  Smaller
values represent more important threads.

c82835a231 rtems: Rework RTEMS API to SuperCore priority

eec08efc90 posix: Rework sporadic server scheduling policy 
Instead of lowering the priority in case the initial budget is consumed
raise the priority for each new period.  Restore the normal priority
once the initial budget is consumed.  This makes it later easier to
combine the high priority phase with temporary priority boosts (e.g. via
priority ceiling and inheritance).

Use the thread lock to protect the POSIX thread attributes instead of
the thread state lock.  This makes it easier to change the thread
priority and keep the POSIX attributes consistent.

Fixes a false positive use of uninitialized variable warning.

2df7fcff88 posix: _POSIX_Mutex_Default_attributes

scheduler instance.  Use INT_MAX to indicate the default ceiling
priority.

ce6e9ec22f posix: pthread_mutexattr_setprioceiling() 
Accept all priority values in pthread_mutexattr_setprioceiling().  This
is in line with POSIX and FreeBSD.  The priority is validated in
pthread_mutex_init().  Validate the priority only for priority ceiling
mutexes.
