    ikev2: in IKE_AUTH responder, handle child sa as a nested state transition
    
    i.e., in IKE_AUTH responder, don't switch to the child part way through
    the transition
    
    - add v2_child_sa_established() to perform transition
    - change the existing half IKE / half CHILD state transition to strictly IKE
    - drop code pexpecting next state to be a child
