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.
