Set to enable support for priority inheritance on mutexes and semaphores.
When this option is enabled, the initial configuration of all seamphores
and mutexes will be with priority inheritance enabled. That configuration
may not be appropriate in all cases (such as when the semaphore or mutex
is used for signaling). In such cases, priority inheritance be be
disabled for individual semaphores by calling:
int ret = sem_setprotocol(&sem, SEM_PRIO_NONE);
And for individual pthread mutexes by setting the protocol attribute
before initializing the mutex:
int ret = pthread_mutexattr_setprotocol(&attr, PTHREAD_PRIO_NONE);
