Assign the specified `newKey` value to the pair identified by the specified `reference`, moving the pair within the list as necessary. Search for the new position from the back of the list (in descending order by key value). Load into the optionally specified `newFrontFlag` a `true` value if the new location of the pair is the front of the list. Return 0 on success, `e_NOT_FOUND` if the pair referred to by `reference` is no longer in the list, or `e_DUPLICATE` if the optionally specified `allowDuplicates` is `false` and `newKey` already appears in the list.
