Source/WebCore:

Export more required headers:
* WebCore.xcodeproj/project.pbxproj:

Flesh out many of the pure virtual methods on IDBBackingStoreInterface, as well as
the RecordIdentifier and Cursor classes:

* Modules/indexeddb/IDBBackingStoreInterface.h:
(WebCore::IDBBackingStoreInterface::RecordIdentifier::~RecordIdentifier):
(WebCore::IDBBackingStoreInterface::Cursor::~Cursor):

Use IDBBackingStoreInterface, IDBBackingStoreInterface::RecordIdentifier, and
IDBBackingStoreInterface::Cursor wherever possible:
