 *  _Message_queue_Submit
 *
 *  This routine implements the directives rtems_message_queue_send
 *  and rtems_message_queue_urgent.  It processes a message that is
 *  to be submitted to the designated message queue.  The message will
 *  either be processed as a send send message which it will be inserted
 *  at the rear of the queue or it will be processed as an urgent message
 *  which will be inserted at the front of the queue.
 *
 *  Input parameters:
 *    id          - pointer to message queue
 *    buffer      - pointer to message buffer
 *    size        - size in bytes of message to send
 *    submit_type - send or urgent message
 *
 *  Output parameters:
 *    RTEMS_SUCCESSFUL - if successful
 *    error code       - if unsuccessful
