* Before the row can be stored in the destination dataset,
* we should
* - Ensure that at least a stub of this defined meaning exists
* - make sure that the row refers to the dmid in the *destination* dataset (dc2),
* instead of the source dataset (dc1).
* - returns True if the defined meaning was already_there().
* @param &$row : row to operate on, passed by reference
* @param $dmid_colum: a column in said row, containing the dmid to operate on
* @param $full=false (optional) : if true, does a dup instead of a dup_stub
* @return true if the updated dmid already existed in the destination (dc2) dataset before now
* false if it did not, and we just created it
