 posix: Simplify message queues

 The mq_open() function returns a descriptor to a POSIX message queue
 object identified by a name.  This is similar to sem_open().  In
 contrast to the POSIX semaphore the POSIX message queues use a separate
 object for the descriptor.  This extra object is superfluous, since the
 object identifier can be used directly for this purpose, just like for
 the semaphores.

 Update #2702.
 Update #2555.
