* multipurpose binaries (symlinks) suck when used with autotools
* swapoff shares small subset of the code with swapon
* usage() and 'struct option' is unnecessary complex when shared
* shorter and simple code is easer to maintain...

For: util-linux
This patch adds a tiny tool "wdctl" which may be used to query the
status of Linux watchdog devices (/dev/watchdog).
This will simply query all fields that may be queried from the
device and print them nicely formatted.

Now we have three versions of the mount(8) utility
* old mount(8)
--enable-mount [default]
* old mount(8) linked with libmount
This is this is necessary for systems without mtab file.
--enable-libmount-mount
- new mount(8)
This is completely new pure-libmount based mount(8).
--enable-new-mount

This program uses the prlimit() system call to get and/or set resource limits
for a given process.

chcpu can modify the logical state of CPUs. It can enable and disable CPUs,
scan for new CPUs, change the CPU dispatching mode of the underlying
hypervisor and request (configure) or give logical CPUs back (deconfigure)
to the the underlying hypervisor.
This is quite useful if you work a lot with virtual servers, since doing all
the configuration stuff directly via sysfs becomes a pain.

This is libmount based re-implementation of the mountpoint(1) command.
The original implementation is maintained in sysvinit suite.
The mountpoint(1) in util-linux is not enabled by default (for now) --
use --enable-mountpoint to enable the util.

fstrim is used on a mounted filesystem to discard (or "trim") blocks
which are not in use by the filesystem. This is useful for
solid-state drives (SSDs) and thinly-provisioned storage

The fallocate(1) utility is used to preallocate blocks to a file.
This can be useful for virtual images, database files, testing, etc.
Normally we'd hope that various tools will start using preallocation
internally, but until then such a utility may be useful, and could be
scripted as well.
The original Eric's version is available at:
http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/2490
This version:
- checks for fallocate glibc function and kernel syscall
- does not provide a fallback and does not call posix_fallocate()
- adds long options
- uses err.h for errro messages
- adds NLS support
- cleanups man page
