	* rr.c (gnuext_live): New variable.
	(rrip_work): Comprehend AU, TR, MD, and FL, all as GNU
	extensions.  Recognize GNU extension id field when processing ER
	fields.
	(release_rrip): Free RR->trans if it's live.
	* inode.c (read_disknode): Interpret and install the values set by
	AU, TR, MD, and FL extensions.
	(diskfs_node_norefs): Free NP->translator if it's set.
	* isofs.h (struct disknode): New members `translen' and
	`translator'.
	* rr.h (struct gn_au, struct gn_tr, struct gn_md, struct gn_fl):
	New strucures.
	(GNUEXT_SRC, GNUEXT_DES, GNUEXT_ID, GNUEXT_VERS): New macros.
	(struct rrip_lookup): New members author, translen, trans,
	allmode, flags.
	(VALID_AU, VALID_TR, VALID_MD, VALID_FL): New macros.

	* Makefile (DIST_FILES): Add, referring to EXTENSIONS.
	* EXTENSIONS: New file.
