This feature allows to call multiple independent fsck instances rather
than use only one "fsck -A" process.
The lock uses LOCK_EX flock(2). The lock request is ignored if the
whole-disk is non-rotating disk. The verbose mode (-V) provides
information about disk locking.
Note that "fsck -l" does not care if the device is stacked, for
example if you want to call "fsck -l /dev/md0" and "fsck -l /dev/md1"
then the underlying devices will not be locked. The traditional "fsck
-A" does not run in parallel for stacked devices.

The current heuristic for conversion from partition to whole-disk
is based on device names. It's pretty poor. This patch replaces this
code with blkid_devno_to_wholedisk(). This solution is based on
/sys FS and it works for arbitrary partitioned devices.
The another problem is the way how fsck determines stacked devices.
The current code checks device name for "md" prefix only. It does not
care about DM, dm-ccypt, and so on. This patch uses
/sys/block/.../slaves/, but it does not fully resolves dependencies
between all devices. The method is simple -- fsck does not check
stacked devices in parallel with any other device.

Rather than each fs util having its own search policy, unify the paths in
configure and allow them to be tweaked by downstream. In the process,
drop the /etc paths as no one has ever really used these.

analog to mount gracefully ignoring non existing devices if the "nofail"
option is specified in fstab, also have fsck -A skip them. This way it's
possible to have devices optionally not available during boot but still
have them fsck'd if they are there.

Some systems define __STDC__ and do not have a working const, some do
not define the macro but do have a working const. Use AC_C_CONST to
check for its presence.

The libvolume_id is deprecated in favor of libblkid. The libblkid from
u-l-ng provides the same functionality as libvolume_id.
