Reviewed by Tony Chang.

Source/WebCore:

Combine abstract interface IDBBackingStore with its only
implementation, IDBLevelDBBackingStore, to reduce code
complexity. The legacy structure existed to support a SQLLite
IDBBackingStore, but it is no longer worth the complexity to
support this abstraction.

Changes include:
1) Merging IDBLevelDBBackingStore into IDBBackingStore.

2) Merge together IDBBackingStore's inner classes: Cursor,
Transaction, and ObjectStoreRecordIdentfier with their respective
subclasses in IDBLevelDBBackingStore.

3) Simplifying the inner Transaction class to not be refcounted or
virtualized, to allow it to be a simple concrete member of its
owner, IDBTransactionBackendImpl.

No new tests as this is purely a refactor.
