btrfs-progs: fi usage: print ratio of used/total for each chunk type
...
This is based on idea from Stanislaw Gruszka to print the ratio,
originally suggested for the 'fi df', but we don't want to add new
things there and let people use 'fi us' instead. The new output fits
there and is printed by default without options:
Example output:
$ btrfs fi us /mnt

btrfs-progs: fi usage: sort table by device id
...
The result of 'btrfs fi usate -T' looks strange when the devices are
sorted by path and not by id. It's harder to lookup and the device id
reflects "the order of appearance" in the filesystem.
