With this new protocol version the target watches the size of the
received messages while reassembling an upgrade block.
If a message of the header size arrives and it is not the last message
of the block, the target considers it a re-start of the block transfer
by the host (presumably because a chunk was lost and the host did not
receive a confirmation of the block transfer in the preceding block
transfer attempt.)
BRANCH=none
BUG=chrome-os-partner:52586
TEST=the upgrade command on the host reports target running protocol
version 2, upgrades on B1 board still run smoothly.
