Now the internal API uses loopcxt_set_...() to set context variables
as well as to call ioctls. This patch introduces loopcxt_ioctl_...()
to makes things more obvious to readers.

losetup: dummy: Warning: file does not fit into a 512-byte sector; the end of the file will be ignore
The warning is bogus as with offset the size of the file fits into
512-byte sector. Simple test that all is right:

This patch add to support for remount-all operation to
libmount and mount(8).
For example:
mount --all -o remount,ro -t vfat
to remount read-only all VFAT filesystems.

* 'time-fixes' of https://github.com/kerolasa/util-linux:
fsck.cramfs: use utimes() instead of utime() that is obsolete
hwclock: use monotonic time to measure how long setting time takes
include: add indirect monotonic clock id specifier
timeutils: match today day and this year correctly
Ensure utmp user name field is null terminated. Without that getpwnam() can
buffer overflow, when wtmp file is malformed.

Earlier gettimeofday() was affected by discontinuous jumps. Measuring how
long time it takes to set time using function that effected by the very
thing being measured makes head spin. Lets make this less confusing with
monotonic clock that ticks on without jumps.

Assumption all years since 1970 have been exactly 365 days long has it's
problems when leap years happen. Lets use struct tm fields that are
provided by localtime_r(), making year and day to be correctly compared even
when it's late new years eve somewhere else than UTC-0.

This new variable allows to keep lastlog file small and filter out
things like huge nfsnobody UIDs.
The variable is also supported by shadow-utils (adduser, etc.).

ENV_SUPATH and ENV_ROOTPATH are equivalent and ENV_ROOTPATH takes
precedence in both login and su. It makes no sense. More logical would be
precedence of ENV_SUPATH in su and ENV_ROOTPATH in login.
Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>
su(1) documentation says:
/etc/default/su command specific logindef config file
/etc/login.defs global logindef config file
It indirectly indicates that /etc/default/su should take precedence
over /etc/login.defs.
But the reverse is true. It is not possible to define ENV_PATH in
/etc/login.defs and then make su specific customization in
/etc/default/su. We need to change read order to match the documented
behavior.

blkid(8) in high-level mode checks partitions and unpartitioned
whole-disk devices from the file /proc/partitions.
The current heuristic assumes that partition name ends with a digit.
Unfortunately, this is not correct -- for example md0 or nvme0n1 are
whole-disk devices.
This commit uses sysfs_devno_is_wholedisk() to make sure the device is
a partition (according to kernel or DM). It's probably more expensive,
because this way requires more syscalls (to read stuff from /sys etc.).
The patch also adds more information to the blkid(8) man page.

When providing an abbreviation of the level name with the option "-n, --console-level level",
it corresponds to the level (included) up to which messages are displayed on the console.
If a level number is given, this level is excluded.
So in the given example, "-n 1" is equivalent to "-n emerg".
