* 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.

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
sr0 11:0 1 1024M 0 rom
└─pktcdvd0 252:0 1 0B 0 disk

We also need reference from child to parent to implement multi-parent
view. This change allows to walk on tree in both directions.

The target use-case are systems with large number of multi-path
devices or systems with duplicate (copied) filesystems.
The feature is flexible enough to use arbitrary column (for example
WWM or UUID, ...) as de-duplication key.
For example tree with multi-path devices sd{c,d,e,f}
./lsblk
