This caused FTBFS bugs on AMD64 platforms, since it uses a different
64-bit type when compared with IA64, so we need to make our
autoconfiguration system more intelligent.

Make the libdevmapper fail quietly if blkid is called without root
privileges or the kernel does not include device mapper support.
(What is the device mapper _library_ doing writing to stderr, anyway?)

Users have reported problems on newly installed systems when the
Macintosh's system clock battery is dead and the hardware clock is
returning a date of 1904. Turns out there were some bugs in handling
dates before the Unix epoch.

probe.c (blkid_verify): Fix the bid_time sanity checking logic,
so that if last verification time is more recent than the
current time, or the comparison between the last
verification time and the current time causes an overflow,
a device verification will take place.
devname.c (blkid_get_dev): Set the initial bid_time to be
INT_MIN, to guarantee that blkid_verify will always be run
even when the system clock is insane.
dev.c (blkid_debug_dump_dev), read.c (debug_dump_dev),
save.c (save_dev): Fix the printf format for dev->bid_time
to match the fact that it is an signed type.

If the filesystem has an external journal, store the UUID of the
external journal in the tag EXT_JOURNAL.
If the filesystem type has changed, clear all the tags on the device,
not just a preset list of LABEL, UUID, TYPE, and SEC_TYPE.
Fix a bug so that blkid_set_tag will work correctly when freeing a tag
when the input name parameter comes from the tag that we are freeing.

The current libblkid code expects that there's magic string in FAT super
block (like "FAT12", "FAT16", ...). It's very often right, but valid FAT
super block may be without magic string too :-(
The patch from attachment fix this problem. It's inspired by HAL and
Linux kernel.

There's mistake in blkid ext2 detection code. The libblkid doesn't
check for journal when revalidate the cache information about an ext2
device.
# rm -f /etc/blkid.tab
# mkfs.ext2 /dev/loop0 &> /dev/null
# blkid -s TYPE /dev/loop0
/dev/loop0: TYPE="ext2"
# mkfs.ext3 /dev/loop0 &> /dev/null
# blkid -s TYPE /dev/loop0
/dev/loop0: TYPE="ext2"
That bug doesn't appear when libblkid creates new cache and checks for
all possible filesystems, because it tries ext3 before ext2. BUT when
the library only revalidate the cache it first probes for old cached
filesystem (e.g. ext2).

Similarly, the blkid library will now return an ext3 type for ext 2/3

We allow files to be probed by the blkid library, to make it easier to
