Reviewed by Tony Chang.

Source/WebCore:

IndexedDB should allow multiple transactions to run in parallel within and
across databases within an origin. As an initial step to enabling this, the
backing store should not hold a "current transaction" - instead, operations
should be done relative to a transaction managed by the database.

No new tests - no functional changes.
