sem_read_lock

This class allows a semaphore to be auto-locked within a scope. When an os_sem_read_lock is constructed with a reference to a semaphore, the os_sem_read_lock calls read_lock() on its associated semaphore. When an os_sem_read_lock is destroyed, it calls read_unlock() on its associated semaphore. An os_sem_read_lock is merely a helper class and does not own its semaphore.
