    Add protocol to handshake between nodes · 4f327e1b
    Julien Muchembled authored
    There is a need to be able to extend the protocol without breaking
    compatibility with old nodes. This is done by sending version.protocol
    during inter-node handshake, in seqno 1 and seqno 2, so that a node
    knows what version the peers speak and use appropriate format.
    This is implemented with partial backward compatibility: handshake with
    an old node succeeds when the new node does not have to send seqno 1.
