This changes the destroy_link_manager() function to: * call a new function message_get_unlock() to unlock the sending thread from its blocking message_get() * calls pthread_cancel() on the receiving thread, because this unlocks any blocking read from a file descriptor The same message_get_unlock() function has been added ringbuffer_queue to keep the interfaces the same (it does nothing, because ringbuffer_queue is non-blocking).
