libflash/mbox-flash: Update to V2 of the protocol
Updated version 2 of the protocol can be found at:
https://github.com/openbmc/mboxbridge/blob/master/Documentation/mbox_protocol.md
This commit changes mbox-flash such that it will preferentially talk
version 2 to any capable daemon but still remain capable of talking to
v1 daemons.
Version two changes some of the command definitions for increased
consistency and usability.
Version two includes more attention bits - these are now dealt with at a
simple level.
