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

Lets not assign *info_ptr to 0 before calling free on it and lose
track of already allocated memory if realloc fails in
add_info_to_list. Lets call free first.

The usage() calls exit() internally, so remove the return after it.

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.
