function in get_device_by_label.c to allow the use of
UUID= or LABEL= when creating filesystems which use external
journal dev (e.g. mke2fs -J device=LABEL=<journal_label>).
tune2fs.c: Use superblock s_journal_uuid to locate an external
journal device instead of s_journal_dev when removing it.
Allow opening journal devices to set the label and UUID
in the ext2 superblock.
mke2fs.c, tune2fs.c: Free journal_device after use, as it is
malloc'd in interpret spec.
get_device_by_label.h (get_volume_label_by_spec): Add function prototype.
get_device_by_label.c: Use string_copy() instead of strdup() for
portability's sake. Fix a few other gcc -Wall complaints.
fsck.h, fsck.c (string_copy): Export string_copy() extern.
badblocks.c: Fix various gcc -Wall complaints, including an incorrect
reference to sync in flush_bufs().
ChangeLog, configure, configure.in:
configure.in: Add checks for the header files sys/mkdev.h and
sys/sysmacros.h.
fsck.c: Added support for LABEL= and UUID= specifications for the
filesystem's device, to match what recent mount programs can support.
Also, close stdin when doing fsck -A or when checking more than one
filesystem at a time, so that e2fsck doesn't try to ask interactive
questions if the filesystem appears to be mounted.
get_device_by_label.c: New file added to support LABEL=foo and
UUID=bar type specifications.
