Combine the code for opening readable and writable databases. This improves the handling of the case where a database cannot be opened because it cannot be upgraded. Previously we would open the database twice: first read-write, then read-only, each time failing due to the version check. Now only open it once. Removed the goofy locking logic related to upgrading a read-only database to read-write. We now do it in place by reopening the necessary connections in the connection pool.
