losetup: add --list and --output option
The --list --all is the default output:
# losetup
NAME SIZE OFFSET AUTOCLEAR RO BACK-FILE
/dev/loop0 0 0 0 0 /home/fs-images/swap.img
/dev/loop1 0 100 0 0 /home/fs-images/disk.img
[kzak@redhat.com: - default to --all if no device specified,
- cleanup column names (add BACK- prefix)
- add MAJ:MIN to of the loopdev device]
