This patch introduces two new parameters to set the
user ID and the group ID of the program to be executed.
Setting group ID also drops supplementary groups.
The option names used are the same as for nsenter,
-S, --setuid and -G, --setgid.

This patch instroduces two new parameters to set the new
root and the new working directory in this new root.
This allows to combine "unshare chroot" in one command,
and doing like this the /proc filesystem is correctly
mounted in the new root with "--mount-proc".
The new parameters are -R, --root and -w, --wd. The names
are the same as for nsenter, except for "-r" that is already
used by "--map-root-user" and replaced by "-R".

The code and man page do not assume -s to be short alias to
--setgroups.
This commit also a little bit change --help output formatting to make
it more readable and structured.

This broke compilation when HAVE_POSIX_FALLOCATE was undefined. The typo
dates to the original posix_fallocate support added in commit
833f9a7aae.

Clear environment in way like su(1), but PATH is set to hard-coded
defaults and /etc/login.defs is not used at all (I guess we want to
keep setpriv(1) simple).
If you need anything more advanced than use env(1).

Replace -a with -A to discard mounted filesystems from /etc/fstab. The
original -a forces fstrim to try to discard all filesystems, including
for example manually mounted removable media.
It seems better for widely used .service unit to follow /etc/fstab.

It's kernel business to return EINVAL for unsupported RTC_UIE_ON. We
(userspace) should not make decisions about things that we do not
control.
If kernel is wrong then fix the kernel, don't hide the problem by
crazy ifdefs in userspace.

The command umount supports things like --all-targets and --recursive
to umount all nodes in specified tree. Sometimes it makes sense to
aggressively use wildcards like /dev/sdb* and in this case --quiet
seems like a good choice
umount --quiet --all-targets /dev/sdb*
to suppress 'not mounted' error messages. The new option suppress only
these error messages and nothing else.

It seems better to use generic "NTP daemon" in the man page than
points to specific ntpd(1) implementation as some distros use for
example chronyd(1) rather than old ntpd(1).

Some mistakes happened lately when switching from path_exist()
to ul_path_access(). See f09a98de and 8ca31279.
This caused ipcs test failures when running i386 binaries on x86_64
hosts, because the syscall fallback was always used. That's why I
reviewed all similar changes and found another one in chmem.

* use ul_path_* API for /sys/devices/system/cpu paths
* use ul_path_* API for /proc
* rename is_compatible() to is_devtree_compatible() as it works
with the devices tree only
