    whack: update oppo options and corresponding whack message fields
    
    - add --opposport
    - make passing reference to all --oppo* options in
      in documentation and usage messages
    
    In pluto, pack all the information provided by whack into
    ip_endpoints.
    
    Since everything defaults to zero this doesn't alter current
    behaviour.
