    ikev2: add a custom IKE_SA_INIT REDIRECT response processor
    
    - so that retransmits continue when the redirect is invalid,
      return STF_IGNORE when the reject is rejected
    
    - so that retransmits are canceled and things are cleaned up,
      return STF_OK when the redirect is accepted
    
    - set the state transition timeout to EVENT_v2_REDIRECT
      so the redirect event is immediately triggered
    
    The redirect event handler then deletes the state like before.
    
    (This makes for an interesting contrast to the COOKIE and
    INVALID_KE_PAYLOAD processors which force an event)
