        IndexedDB: Support LevelDB transactions.
        https://bugs.webkit.org/show_bug.cgi?id=61270

        Introduce LevelDBTransaction, which implements in-memory transaction
        support on top of LevelDB, and hook this up for IndexedDB to use.

        This is all covered by existing tests.
