ChangeLog, Makefile.in, dumpe2fs.c, jfs_user.h, mke2fs.c, tune2fs.c:
  tune2fs.c: Changed the external journal code so that it simply adds a
  	filesystem to a journal; the journal must have bene created via
  	"mke2fs -O journal_dev /dev/XXX".
  mke2fs.c: Add support for creating an external journal device by using
  	the command "mke2fs -O journal_dev /dev/XXX".  Also changed the
  	external journal code so -j device=/dev/XXX it simply adds a
  	filesystem to that journal; the journal must have been created via
  	separate step.
  dumpe2fs.c (print_journal_information): Add support for dumping
  	information about an external journal device.
