The original Julian's hardlink.c code is pretty readable, but for
util-linux we use a little different indention (aka Linux kernel
coding style).

We usually use "debug" for very detailed information. For end-user
information is better to talk about "verbose" output.

The current version used in util-linux is based on original code from
Jakub Jelinek.
The new version is based on Debian implementation from
https://salsa.debian.org/jak/hardlink. This new version uses nftw()
to walk on directories tree and organize internal data binary tree
(tsearch() and twalk()). This new version provides more features like
--ignore-{mode,owner,time}, --respect-xattrs, --respect-name,
--include, --keep-oldest, --minimize, --maximize, etc.
Note that the new version uses -f for --respect-name, the old version
uses -f to hardlinking across filesystems (very probably rarely unused
feature).

It might be useful for security auditing purposes list all possible
mount flags/options including default set which are normally not listed.
This patch adds "--vfs-all" option to list all fs-independent flags
on VFS-OPTIONS column, as well as libmount funcionality to accomplish
it.
i.e.:
$ findmnt -o VFS-OPTIONS
VFS-OPTIONS
rw,relatime
rw,nosuid,nodev,noexec,relatime
rw,nosuid,nodev,noexec,relatime
ro,nosuid,nodev,noexec
...
$ findmnt --vfs-all -o VFS-OPTIONS
VFS-OPTIONS
rw,exec,suid,dev,async,loud,nomand,atime,noiversion,diratime,relatime,nostrictatime,nolazytime,symfollow
rw,noexec,nosuid,nodev,async,loud,nomand,atime,noiversion,diratime,relatime,nostrictatime,nolazytime,symfollow
rw,noexec,nosuid,nodev,async,loud,nomand,atime,noiversion,diratime,relatime,nostrictatime,nolazytime,symfollow
ro,noexec,nosuid,nodev,async,loud,nomand,atime,noiversion,diratime,norelatime,nostrictatime,nolazytime,symfollow

It displays filesystem root attached to system, for example
btrfs with two mounted subvolumes:

* add libmount FS to struct lsblk_device
* add new column MOUNTPOINTS (pl.) with multi-line cells to display
all mountpoints relevant for the device
* the old MOUNTPOINT is backwardly compatible and it (usually) displays the
last device mountpoint from /proc/self/mountinfo
For example btrfs with more subvolumes:
$ lsblk -o+MOUNTPOINTS /dev/sdc1
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT MOUNTPOINTS
sdc1 8:33 0 50M 0 part /mnt/test /mnt/A
/mnt/test
/mnt/B
Note, in this case MOUNTPOINT displays mount point where is mounted
root of the filesystem.

GNU libc's getopt_long(3) have the tradition of not shuffling arguments
to find options when either POSIXLY_CORRECT is defined in environment
variables or '+' prepended in short options. Hence, the current code
base is fine as is fine as is for util-linux built with GNU libc.
However, musl libc only honour POSIX convention when short options
prepended with '+'. musl libc doesn't care about POSIXLY_CORRECT.
Thus, the behaviour of util-linux's getopt(1) that linked with musl-libc
doesn't match with its own documentation.
Let's make sure a '+' is always prepended to short options if
POSIXLY_CORRECT is defined.

build-sys: sort various lists in configure.ac
mkswap: tell how to fix insecure permissions and owner in warning
lsipc: make default output byte sizes to be in human units
man: add missing backslash to caret printing macro
lscpu: fix variable shadowing

We encode to "safe" strings almost all variables for 'blkid -o udev'
and we need it also for SYSTEM_ID, PUBLISHER_ID, APPLICATION_ID,
BOOT_SYSTEM_ID and recently added VOLUME_SET_ID and DATA_PREPARER_ID.
This change makes blkid from util-linux more compatible with built-in
udevd blkid.

The shells are very restrictive about variable names, only [:alnum:]
chars are allowed (and alphabetic chars as the first char). The
library will replace "bad" chars with "_". The char '%' at the end is
replaced by _PCT.

This is unnecessary, we have ${docsdir}/util-linux which is good
enough for these two getopt examples. I guess the "getopt"
subdirectory is legacy from time getopt has been merged into
util-linux.

This dependence is defined by
$ cat /sys/class/pktcdvd/device_map
pktcdvd0 252:0 11:0
Unfortunately, there is not any direct sysfs way how to refer this
relationship in /sys/{block,dev/block}. So, we have to read the
device_map file and then compare device numbers with the list.
$ lsblk /dev/sr0
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

Limiting random query to 1000 uuid's was pointless when the next line will
further restrict upper limit to 63 entries. The 63 entries is what fits to
the uuidd communication buffer with the header.
