Added support for simple binary semaphores in addition to the high
power binary/mutex style semaphores already supported by RTEMS. This was done at the request of Eric Norum <> in support of his effort to port EPICS to RTEMS. This change consisted of changing the nesting_allowed boolean into a lock_nesting_behavior enumerated value as well as allowing the core mutex object to optionally support ensuring that the holder of a binary semaphore released it. Finally, a more subtle enhancement was to allow the non-holder to release a priority inheritance/ceiling mutex and still allow the holding task to return to its original priority.
