This moves certain properties into a second part of the buffer that isn't visible to the first with the intention of making a backwards compatible MP protocol that can have more efficient encoding in a second part that is after MsgLen. Unfortunately this doesn't work because the code ensures that MsgLen in the header matches the received byte count.
