Releases a single unit to a specified semaphore. If threads are waiting at the semaphore, the thread at the head of the queue is awakened and given the unit.

Warning: If this function is invoked on a semaphore that contains the maximum of 65,535 units, the number of units in the semaphore is not incremented, and the results will be unpredictable.

Note:   This is a signaling call; call knStopRtScheduler in interrupt handlers before using this call.
