    tdf#160196 add /AF entry to catalog, enable assoc. files in PDF/A-3
    
    PDF 2.0 introduced "associated files" entry. Add the association
    for the attached files to the /Catalog (/AF entry) and make sure
    the /AFRelationship is set to /Source.
    
    Also enable this for PDF/A-3 (where this was apparently added),
    as this is required.
