The current --target <path> implementation check the <path> elements in
reverse order to get the mountpoint. The feature may be inwanted in
some cases when we really want to check for mountpoint specified by
the <path>. The new option "--mountpoint <path>" allows to be strict.

The overlay filesystem does not provide usable st_dev (in traditional
UNIX way). It's necessary to search in /proc/self/mountinfo to detect
which path element is mountpoint.
$ findmnt --target /mnt/merged/dir-a/foo
TARGET SOURCE FSTYPE OPTIONS
/mnt/merged overlay overlay rw,relatime,lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work

Transform some of them into copyright lines.
Also fix three header lines and snip some trailing whitespace.

As per the convention shown in Documentation/howto-man-page.txt.
Also make a few other tiny adjustments along the way.

* in some cases is realpath() overkill
* sometimes you want to search for explicitly specified paths (e.g.
"findmnt --fstab /mnt/symlink") rather than for real paths
* you want to avoid readlink() and stat() on NFS

Provide display of filesystem attributes from statvfs(3). These are all
displayed in human readable format.

If you really need to store your configuration to a alternative files
then you have to explicitly specify the files or directories on
mount(8) command line by --fstab option.

The optional argument for -s, --fstab options (--fstab=file) is not
backwardly compatible, because command line with short options (e.g.
findmnt -snr) will be interpreted incorrectly.
This patch removes support for the optional --fstab argument and
introduces a new option --tab-file, for example:
findmnt --fstab --tab-file=/etc/fstab.foo

Examples:
* findmnt --fstab -O noauto
Returns all entries where is not "auto" option (including entries
with "noauto" option.
* findmnt --fstab -O +noauto
Returns all entries where is literally "noauto" option.

Use dates without the day, use the full month name, put "util-linux" in
the lower left corner, and "User Commands" or "System Administration"
at the top center.
Also improve here and there the one-line program description.

This patch modifies the default output for SOURCE column. All btrfs
subvolume mountpoints and all bind-mount (where source is not root of
FS) will be printed as:
SOURCE TARGET
/dev/sda1[/aaa] /mnt/test
where /aaa is subvolume name or fs root for bind mounts, it means:
# mount -t btrfs /dev/sda1 /mnt/test -o subvol=aaa
or:
# mount --bind /aaa /mnt/test
The info about fs-root is 4th column in /proc/self/mountinfo.
