btrfs-progs: qgroups-usability

From: Jeff Mahoney <[email protected]>

Changes since v2:
- Updated Reviewed-by tags were provided.
- Fixed the typoed commands that I commented on in the previous posting.
- Dropped the btrfs_cleanup_root_info since it's unnecessary with the switch to libbtrfsutil.
- Updated the qgroups pathname patch to use libbtrfsutil
- Added a mini-filter to skip dead qgroups in 'qgroup show' output unless -v is specified.

The most notable change is that this posting doesn't include the JSON format patches since there was still some open discussion there. The plumbing for passing global options around to commands is there, so we really just need to decide on how we want to handle alternative formats. For some commands, the formatting library that coreutils uses will probably work but for qgroups show to represent nested groups, it's unsuitable.

I've also posted this as a pull request to the devel branch:
