[PATCH v2 0/4] btrfs-progs: Use common function to parse unit arguments

[Zhao Lei <zhaolei@cn.fujitsu.com>]

We are using separate code for parse unit mode in current code,
better to use common function.

This patchset introduce common function to parse arguments for setting
unit: get_unit_mode_from_arg()
and common help message for unit argument, to make every tool in btrfs having
same interface for setting unit.

The merit are:
1: Unify current each tool's arguments for unit
2: Make tools in future easy to implement such argument
3: Changes(enhancement) in common function have effect on all
   relative tools

Changelog v1->v2:
 Keep short options for 'fi df' command, to keeps option compatibility
 with the standalone 'df' commmand, suggested-by:
 David Sterba <dsterba@suse.cz>
