New utility allows to run process with separate mount, UTC, IPC or
network namespaces.
[kzak@redhat.com: - some cosmetic changes in usage() and err() usage
- move "if BUILD_UNSHARE" to separate place in Makefile.am
- add unshare to .gitignore]

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

This reverts commit 98c7944b52.
Unfortunately, the patch has been committed by "git commit -a" and
includes unwanted changes in configure.ac and sys-utils/Makefile.am...
Sorry.
* use "filesystem" everywhere (currently, the mount.8 man page is inconsistent
and uses "file system" and "filesystem")
* fix "The extN" to "The extN filesystem" (reported by Theodore Tso)

The others utilities are in one of the top-level directories. That's
confusing to have blkid(8) and findfs(8) in shlibs/ tree.

We need to use $usr{bin,sbin,lib}execdir variables in *.pc.in files
and these files are generated by ./configure script.

Supported scenarios:
* internal libblkid (--enable-libblkid, default)
* external libblkid (--disable-libblkid)
- systems without pkg-config
- systems with pkg-config
* systems without libblkid at all
(requires --disable-mount and --disable-fsck)

Supported scenarios:
* internal libuuid (--enable-libuuid, default)

- systems without pkg-config
- systems with pkg-config

When building util-linux-ng-2.15, I get this:
../lib/fsprobe.c:10:19: error: blkid.h: No such file or directory
Unfortunately, the blkid.pc uses -I${includedir}/blkidi since
e2fsprogs v1.41.2. The old versions use -I${includedir} only.

"SPEC" is usually used in mount(8) as a generic term for device name or
tag (LABEL, UUID). The function blkid_evaluate_* works with TAGs only.

It seems better to split SONAME and the public library version. The
library version will be the same as util-linux-ng PACKAGE_VERSION.
PACKAGE_VERSION: <maj>.<min>[-<suffix>] e.g. 2.15-rc2
Symbols versioning: BLKID_<maj>.<min> e.g. BLKID_2.15
blkid_get_library_version(): <maj>.<min>.0 e.g. 2.15.0
SONAME: libblkid.so.1
See also the original patch a0487b1cb5
where was introduced library versioning.

For compatibility with e2fsprogs tree:

e2fsprogs: blkid.static make target
Nice for testing w/o needing to swizzle around system
libraries...

It seems that blkid.pc from e2fsprogs has been fixed:
$ pkg-config --libs blkid
-lblkid
and the pkg-config does not return any other extra libraries (such
-luuid or -ldevmapper).

* moves the generic libblkid/libvolume_id wrapper (fsprobe.c) from
mount/ to lib/. We'll use the wrapper in cfdisk and fsck.
The wrapper supports:
- obsolete volume_id (udev)
- obsolete libblkid (e2fsprogs)
- libblkid (util-linux-ng)
* mount, umount and swapon when linked against the new libblkid use
- low-level probing code to read LABEL, UUID or FSTYPE from a device
- high-level blkid_evaluate_spec() to convert LABEL/UUID to devname
Signed-off-by: Karel Zak <kzak@redhat.com>
* cleanup mount/Makefile.am
* add {VOLUMEID,BLKID}_CFLAGS -- necessary for pkg-config
* add support for linking with in-tree libblkid
