    demux: add msg_digest .fake_dne, set when creating a fake_md
    
    This way v2_msg_role() can treat a NULL MD and a fake MD the same
    and return NO_MESSAGE - which is true because the fake_md gets
    created when there isn't a message.
    
    Note that this is different to is_msg_{request,response}() which
    just look at the flags in the header.
