* A mailbox is an asynchronous communication mechanism.<br>
* The following operations are possible on a mailbox:
* - <b>Post</b>: Posts a message on the mailbox in FIFO order.
* - <b>Post Ahead</b>: Posts a message on the mailbox with high priority.
* - <b>Fetch</b>: A message is fetched from the mailbox and removed from
* the queue.
* - <b>Reset</b>: The mailbox is emptied and all the stored messages lost.
* .
* A message is a variable of type msg_t that is guaranteed to have the
* same size of and be compatible with pointers (an explicit cast is needed).
* If larger messages need to be exchanged then a pointer to a structure can
* be posted in the mailbox but the posting side has no predefined way to
* know when the message has been processed. A possible approach is to
* allocate memory (from a memory pool as example) from the posting side and
* free it on the fetching side. Another approach is to set a "done" flag into
* the structure pointed by the message.
