Btrfs: separate out tests into their own directory
The plan is to have a bunch of unit tests that run when btrfs is loaded when you
build with the appropriate config option. My ultimate goal is to have a test
for every non-static function we have, but at first I'm going to focus on the
things that cause us the most problems. To start out with this just adds a
tests/ directory and moves the existing free space cache tests into that
directory and sets up all of the infrastructure. Thanks,
