Refactor SQLiteOpenHelper.
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.
