MSP messages are passed between processes and also added to a queue at the
receiving end. Some of the structure components are only relevant when it is
being passed, or when it is on a queue.
A received MSP message contains the following information:
- Target queue in this task
- Reply queue in other task
- Actual size of message body
- Message body
- Pointer to next message in the queue
The content of the message body is only understood at higher levels (AMS in
this case) - it is immaterial to MSP.
