    demux: respond to messages from the future using IKEv2

    ikev2: respond to an IKEv++ message with v2N_INVALID_MAJOR_VERSION
    
    Not IKEv1.  Also ignore version=0.  Add notes on how dodgy all
    this is.  For instance, have to assume that MD is an initial
    request.

    ikev2: in send_v2N_response_from_md() don't pexpect() inconsistencies
    
    Code needs to handle an MD from the future - IKEv++.

    ikev2: in open_v2_message() don't call v2_msg_role() to sanity check it is a response
    
    v2_msg_role() expects an IKEv2 message which isn't true when
    responding to IKEv++.  Instead just trust MD!=NULL and assume
    caller knows best.
