     xfstests: btrfs tests for basic informational commands

     Run basic btrfs information commands in various ways, performing
     sanity tests of: filesystem show, label, sync, and device stats
     (sync is included just because it's simple).  These are mostly
     just smoke tests, although for example show by label & UUID
     should verify that the correct fs was shown.

     This also adds quite a few new filters to accommodate the output
     of the new commands.
