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.
