At the moment the IDBObjectStoreBackendImpl generates index data, but that has architectural issues for chromium - specifically because a JS engine (V8 or JSC) needs to be available to extract key data.

Rather than doing it in the backend, we need to create a cursor to iterate through the existing data, creating index data on the fly and notifying the backend, and then call the final success handlers only when this cursor has been exhausted.
