btrfs-progs: qgroups usability

From: Jeff Mahoney <[email protected]>

Hi all -

The following series addresses some usability issues with the qgroups UI.

1) Adds -W option so we can wait on a rescan completing without starting one.
2) Adds qgroup information to 'btrfs subvolume show'
3) Adds a -P option to show pathnames for first-level qgroups (or member of nested qgroups with -v)
4) Allows exporting the qgroup table in JSON format for use by external programs/scripts.
