Replace form_serval_instance_path(), which takes a single 'path' argument, with formf_serval_instance_path() and vformf_serval_instance_path(), which take printf(3)-like arguments. This supports more flexible instance path file names. FORM_SERVAL_INSTANCE_PATH() macro works as before, but reimplemented
