    pluto: simplify state chain code
    
    - made invariant for state chains simpler: always circular
      (except before initialization, which is lazy).
    
    - replace uses of FOR_EACH_ENTRY with FOR_EACH_COOKIE_STATE
      + gets rid of a lot of explicit looping
      + more concise, clearer
      + more precise name
    
    - renamed FOR_EACH_ENTRY_WITH_COOKIE => FOR_EACH_STATE_WITH_COOKIE
      to be more precise
    
    - make macro definitions safer through more parentheses
    
    - move some index variable declarations into FOR head
    
    - fix some spelling
