The patchset enhanced btrfs qgroup show command.
Firstly, we restructure show_qgroups, make it easy to add new features.
And then we add '-p' '-c', '-r',and '-e' options to print the parent
qgroup id, child qgroup id, max referenced size and max exclusive size
of qgroup respectively, add '-F' and '-f' option to list qgroups that
impact the given path.
Besides that, the users may want to sort qgroups according to some items.
For this case, we introduce '--sort' option. With this option, we can sort
the qgroup by qgroupid, rfer, excl, max_rfer and max_excl.
Notice, we force to print result as a table(as david suggest this dosen't matter
for now), and with option '--block-size', user can control to print result,for example,
k,K,m,M,etc.What's more '-h' gives a short cut to allow people to print result in
human readable format size.
