blkid: don't read past end of FAT32 cluster chain
When looking for a volume label on a FAT32 filesystem, blkid does not
correctly handle special cluster values in the range 0x0FFFFFF8 to
0x0FFFFFFF, which mark the last cluster in a chain. As a result, it
begins to read [what it treats as] FAT entries from past the end of the
FAT. Depending on the data read, it may then try to parse random data
from the filesystem (including user files, free space, and other
directories) as though it were part of the root directory.
Because parsing stops early when a volume label is found, the problem
only occurs on filesystems without a volume label. When it occurs, it
may result in a long sequence of lseek and read calls; on an older IDE
drive with a 2 GB FAT32 partition, this amounted to around 3 seconds of
disk I/O.
After patching, blkid stop parsing as soon as it reaches a cluster value
greater than or equal to the number of entries in the FAT.

Add a new '-a' option to view/modify the CPU affinity for an entire
group of threads belonging to a given PID. We create two new
functions, print_affinity() and do_taskset() for code simplification.

zeus@jilguero:~/src/util-linux/schedutils$ ./taskset -a -p 01 3142
pid 3142's current affinity mask: 2
pid 3142's new affinity mask: 1

sfdisk: returns non-zero on failed BLKRRPART ioctl
Make sfdisk(8) return non-zero value on failed BLKRRPART ioctl().
This will happen for either partition table re-reads after partition

The function reread_disk_partition() was changed from 'void' to 'int'
and now returns a result to let the calling functions decide to exit(1).

o Old school introduction back to the top of the source file.
o Indentation changes.
o Removal of void casting.
o Removal of braces from single statements.
o Unified format for comments.
o Comparison with W. Venema's code from 1993 to clean few comment
mysteries.
o Web referrals added to further explanation to near the code or
comments which some could find difficult to understand why.
o Clean up of comments.
o FIXME items added where attention is needed.
o Make functions static.
o Functions with same argument types use same argument order.
o Get rid of classic K&R style function declarations.

libmount: add support for x-* mount comments
The current way how add any comment or extra information to /etc/fstab
is to use comment="" mount option. This is not too elegant and readable
if you want to add more than one comment.
It seems better to add any generic prefix that will be used for all
3rd-party userspace mount options.
Expected syntax is:
x-<application>-<options>[=<data>]
For example:
x-systemd-bar=managed
All x-* options (as well as comment=) are ignored by libmount and not
stored to the mtab file.
