volume_id is now able to read NTFS labels. Not very exciting, but we
keep up to date with the version in HAL. Also __packed__ was needed for
the structs, cause the gcc 3.4 compiled version was no longer working
properly.
Here is a update to extras/volume_id/*
o The device is now specified by the DEVPATH in the environment,
it's no longer needed to pass the major/minor to the callout.
o leading spaces and slashes are now removed from the returned string
and spaces are replaced by underscore, to not to confuse udev.
o Arnd Bergmann <arnd@arndb.de> provided the code to recognize s390
dasd disk labels. The -d switch tries to read the main block device
instead of the partition.

Here is a update, which supports iso9660 and udf labels.
Not very useful in the udev case, but I've added it for hal,
so we just catch up with the latest version.
here is a small udev toy, which enables udev to name partitions by
its filesystem label or uuid's.
The following udev rule:
KERNEL="sd*", PROGRAM="/sbin/udev_volume_id -M%M -m%m -u", SYMLINK="%c"
creates a symlink with the uuid read from the filesystem. If no label or
uuid is found the program exits with nonzero and the rule will fail.
ext2, ext3, reiserfs, xfs, jfs, vfat, msdos volume labels are supported,
ntfs and swap partitions can be recognized.
It's possible to compile with klibc and the static binary takes 13kb.
