tune2fs.8.in: Update man page to reflect the fact that adding or
removing a journal doesn't require running e2fsck.

Remove use of AC_REQUIRE which had been used to prevent AC_CANONICAL_HOST
from being called twice, since it gives recent autoconf programs
heartburn (and doesn't seem to be required anymore), anyway.

e2fsck: If a superblock is specified explicitly by the
user, don't try to automatically fall back to an
alternate superblock.

ismounted.c (check_mntent_file): We now validate the entry in
/etc/mtab to make sure the filesystem is really mounted,
since some broken distributions (read: Slackware) have
buggy boot scripts that don't initialize /etc/mtab before
checking non-root filesystems. (Slackware also doesn't
check the root filesystem separately, and reboot if the
root filesystem had changes applied to it, which is
dangerous and broken.)
