This is simply at start at providing generic interface tests. The only thing is tests so far is the empty database conditions on NewestSha, but it adds infrastructure for creating and opening databases with special type handling based on the database and necessary logic to teardown so multiple backends can be tested simultaneously. This and the next series of commits all discussed with drahn@.
