The main point of this is to load the device and chunk infos at one
place and pass down to the printers. The EPERM is handled separately, in
case kernel does not give us all the information about chunks or
devices, but we want to warn and print at least something.
For non-root users, 'filesystem usage' prints only the overall stats and
warns about RAID5/6.
The sole cleanup changes affect mostly the modified code and the related
functions, should be reasonably small.

The device may not be fully occupied by the filesystem, the value of
Unallocated should not be calculated against the device size but the
size provided by DEV_INFO.

The entire device size may not be available to the filesystem, eg. if
it's modified via resize. Print this information if it can be obtained
from the DEV_INFO ioctl.
Print the device ID on the same line as the device name and move size to
the next line.
Sample:
/dev/sda7, ID: 3
Device size: 10.00GiB
FS occupied: 5.00GiB
Data,RAID10: 512.00MiB
Metadata,RAID10: 512.00MiB
System,RAID10: 4.00MiB
Unallocated: 9.00GiB

Move the command definitions where they belong, keep common 'usage'
functions in cmds-fi-disk_usage.c and add exports.
Rename structures containing 'disk' to 'device'.
Fix whitespace in the modified code.

Add back the original output of the 'btrfs fi df' command for backward
compatibility. The rich output is moved from 'disk_usage' to 'usage'.
Agreed in http://www.spinics.net/lists/linux-btrfs/msg31698.html

Enhance the command "btrfs filesystem df" to show space usage information
for a mount point(s). It shows also an estimation of the space available,
on the basis of the current one used.
