Make it possible to unmount a filesystem on a loop device if it is
specified by associated backing file. It does not attempt to unmount
anything if there are more than one loop device associated with the
given file.
Umount looks for associated loopdevice(s) only if umount is called
with the regular file as an argument.
Before:
mount -o loop -t ext2 img mnt
umount -v img
> Could not find /home/puzel/upstream/util-linux/img in mtab
> umount: img: not mounted
After:
mount -o loop -t ext2 img mnt
umount -v img
> img is associated with /dev/loop0, trying to unmount it
> /dev/loop0 has been unmounted

New usage help screen and print version switch. Also fixes to
exit codes, util linux xmalloc replaced emalloc and every error
print is using libc error function.

When you have more than one resource with the same id (but differing
types) combining -a and -i does not show all resources. This patch
corrects that.

The free() before exit() is not so important, but let's keep the
example code nice and consistent.

The problem with libuuid interface is that it is impossible to
inform the caller of uuid_generate_time() if the UUID was generated
in a safe manner (either via uuidd, or using the global clock state
counter).
This patch introduces new function,
int uuid_generate_time_safe(uuid_t out)
which can report whether the generated UUID is safe.
Signed-off-by: Petr Uzel <petr.uzel@suse.cz>
Having uuid_generate_time and uuid__generate_time at
the same time is confusing. These functions are exported,
but not part of the official API (used by uuidd only).

All compler errors reported by -Wall -Wextra -pedantic are fixed.
The patch also makes fsck to use xalloc instead of it's own malloc.
That will make fsck to exit, which could be good thing, at sections
where it previously did not.
Almost all print outs where touched, where various printfs where
converted to warn or err messages.
Finally theres a fix to counter wrap bug that could (very unlikely)
manifest itself if an user specifies same flag exactly UINT_MAX times.

This is visible on a 2TB disk via lsblk, where a large partition
incorrectly displays as 1.171798692T instead of 1.8T. This is
corrected by using a uint64_t type instead of a simple int --
consistant with the type used in lsblk.c to represent the raw size in
bytes.

Usage output screen got to be completely rewrote. Aim is to
assist user to determe which switches to use without reading
manual page. The change also introduced new option to see command
version.
Determination if the executable name is `page' is now easy to see
in source, and effect of using the name is mentioned in manual
page.
Rest of the change is trivial; exit values to compiler warning
removals, magic constants to preprocessor definitions, symbolic
exit values, comment pretty printing and #endif markups.

It adds the ability to logger to log a message to a udp socket. The -n option
followed by the hostname of the remote host is mandatory to do this. The
optional -P option can be used to change the UDP destination port (default
514). The function udpopenlog is used to open the udp socket. After that
everything works in almost the same way like it does when logging to a UNIX
socket.

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

To avoid a conflict with the warn function from err.h, renamed warn to
