rtems: Rework rate-monotonic scheduler
Use the default thread lock to protect rate-monotonic state changes.
This avoids use of the Giant lock. Split rtems_rate_monotonic_period()
body into several static functions. Introduce a new thread wait class
THREAD_WAIT_CLASS_PERIOD for period objects to synchronize the blocking
operation.
Close #2631.
