NAME
        ApplyTagChanges -- change a tag list based on a second tag list. (V39)

   SYNOPSIS
        ApplyTagChanges(list,changeList);
                        A0   A1

        VOID ApplyTagChanges(struct tagitem *, struct tagitem *);

   FUNCTION
        For any tag that appears in both 'list' and 'changeList', this
        function will change the ti_Data field of the tag in 'list' to
        match the ti_Data field of the tag in 'changeList'. In effect,
        'changeList' contains a series of new values for tags already in
        'list'. Any tag in 'changeList' that is not in 'list' is ignored.

   INPUTS
        list - a list of existing tags (may be NULL)
        changeList - a list of tags to modify 'list' with (may be NULL)
