We have many places in our tests where we create temporary directories, which we later remove (most of the time). We have at least 3 helpers to do this, and various places where it's done ad-hoc (and the cleanup is not always present). To try to reduce the clutter, and make the tests more uniform and readable, this patch introduces two helpers in a new "testutil" package: one for creating and one for removing temporary directories. These new functions are safer, better tested, and make the tests more consistent. All the tests are updated to use them.
