[PATCH 00/14] Enhanced df - followup

[David Sterba <dsterba@suse.cz>]

Hi,

this is a followup to the df (space usage) enhancements, Goffredo's
patches are merged without changes, though the code needs updates.

But, given the patchset size, net benefit of the enriched output and
longstanding need of the update, I've deliberately skipped the process of
incremental rewiew/resend loop that should normally take place and implemented
the changes that were agreed in previous discussions and did code cleanups
along the way.

The basic layout of the command output has been kept, there are some
tweaks or additions.

Changes:
* btrfs filesystem disk_usage - renamed to usage
  * added a section of overall filesystem usage, that used to be in the
    'fi df' output
* btrfs device disk_usage - renamed to usage
  * the device size prints both blockdevie size and the size that's occupied
    by the filesystem
  * device ID is printed
* btrfs filesystem df - reverted to the original output
* btrfs filesystem df - now prints the GlobalReserve info
* units print B for bytes
* the ioctls FS_INFO and DEV_INFO need root (patches sent to drop that
  requirement), so there's a warning printed instead
* no documentation for now

It's not finished, I've tried to scan all the previous iteration of the
patches for the suggested UI tweaks and probably missed some, but IMO in a
state that can go to git and be scheduled for a near release.

The major UI changes are there, we can tweak it further of course.
