    ikev2(?): replace delete_my_family() with delete_ike_family()
    
    - make the IKE SA explicit
    
    - replace bool v2_responder_state with enum send_delete {
      DONT_SEND_DELETE, PROBABLY_SEND_DELETE, }
    
      The assumption that only responders wanted to suppress
      delete requests was wrong - for instance when a CHILD_SA
      initiator detects that a response is syntatically invalid
      the IKE SA is dead and no delete can be sent.
    
    - when IKEv2, always suppress the child's delete (since it
      is redundant)

    state: use .st_dont_send_delete=false to suppress delete
    
    eliminate discard_state(), eliminate change_state(STATE_*SA_DEL)

    ikev2: v2_msgid_switch_responder_from_child() -> v2_msgid_switch_responder_from_aborted_child()
    
    Merge in suppressing delete notify and delete_state(child) since
    both go with the call.
