  ndb - bug#34216
    During TC-take-over (NF) the new-TC builds up a new transaction state
    And commits operation according to this state.
    However, in the new state that is build, the operations does not have to be in same order, as "real" state
    In the multi-update-case, this means that operations can be commit in "incorrect" order
  
    i.e update A, delete A, insert A is normally commited in same order as prepared
        but can be committed in any order
  
    This patch changes TUP handling of these out-order commits, and previous implementation
      could confuse the TUX triggers

        Multi-table updates using ordered indexes during handling of
        node failures could cause other data nodes to fail.

Left in PQ status pending further merges.
