chfn: Make readline prompt for each field on a separate line
When readline is called to get user input, it is called without
a prompt argument. As a result, if the user does not enter anything
for a given field, then the next field is displayed on the same
line, yielding the following output:
$ chfn
Changing finger information for user.
Password:
Name []: Office []: Office Phone []: Home Phone []:
instead of the expected:
$ chfn
Changing finger information for user.
Password:
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
This patch restores the expected behavior by feeding readline with
a character to display as "prompt".

To judge from fc412fe4cee960, back in 2016 it was the latest version
of Ubuntu available on Travis CI. Now build tools there are too old
for testing purposes.
Other than that, Ubuntu Trusty hasn't been supported at https://apt.llvm.org/
since August 2019, which makes it kind of hard at this point to bring the latest clang
along with ASan, UBsan, Msan and libFuzzer to Travis CI.

mountpoints are found.

Commit I made while back and has been part of util-linux v2.30 to v2.35 made
col(1) not to output anything when first line did not have newline character.

This commit fixes the issue. Admittedly the col source code is unnecessarily

should add tests that exhaust all possible input handling including all command

Commit 7a2602f629fe ("blkzone: deny destructive ioctls on busy blockdev")
introduced exclusive mode to open block devices to submit zone management
ioctls. This avoids unintended status change of block devices used by the
system. However, it makes blkzone less usable for testing. For example,
the test case zbd/007 of blktests utilizes blkzone to reset zones of
block devices mapped to dm-linear devices. After the commit, the test
case fails with EBUSY error at blkzone reset, since the system uses the
reset target block device to map to the dm-linear device.
To allow blkzone to change status of zoned block devices used by the
system with intention, introduce --force option. With this option, block
devices are opened without exclusive mode.
Also fix too many periods in man page of --verbose option.

Manual pages: unshare.1: clarify description and example for --mount=<path>
The existing text is not quite accurate, and I recently injected an
error into the EXAMPLES. This patch fixes both issues.
The text in DESCRIPTION incorrectly states that the propagation type of
the parent mount must be "private". This is not accurate. Rather, the
propagation type must be something *other than "shared"* (i.e.,
"private", "slave", or "unbindable").
In the EXAMPLES section, I added text that implies that if the
propagation type of the parent mount is "shared", then the child mount
created by --mount=<path> might propagate to another namespace.
Rather, in this situation, an error would result. Clarify that.

libmount: add support for ID=
This patch add support for a new tag. The tag is based on udev block
device ID (see /dev/disk/by-id). The usual use-case is to use
WWN for this purpose, for example
# mount ID=wwn-0x50026b724b09a1ff /mnt
Note that ID is not strictly defined and udevd generates various IDs
also for HW where WWN is undefined. This is reason why introduce ID=
seems better and more generic than more restrictive WWN=.
