Source/WebCore:

Each IDBOperation has it’s ::perform() moved to a method on IDBServerConnection.
This almost removes all knowledge of the backing stores from the front end.

* Modules/indexeddb/IDBDatabaseBackend.cpp:
(WebCore::IDBDatabaseBackend::clearObjectStore):
(WebCore::IDBDatabaseBackend::runIntVersionChangeTransaction):
* Modules/indexeddb/IDBDatabaseBackend.h:

* Modules/indexeddb/IDBObjectStore.cpp:
(WebCore::IDBObjectStore::clear):

Add methods to reflect each transaction backend operation:
* Modules/indexeddb/IDBServerConnection.h:

Schedule certain operations with callbacks:
* Modules/indexeddb/IDBTransactionBackend.cpp:
(WebCore::IDBTransactionBackend::scheduleVersionChangeOperation):
(WebCore::IDBTransactionBackend::schedulePutOperation):
(WebCore::IDBTransactionBackend::scheduleOpenCursorOperation):
(WebCore::IDBTransactionBackend::scheduleCountOperation):
(WebCore::IDBTransactionBackend::scheduleDeleteRangeOperation):
(WebCore::IDBTransactionBackend::scheduleClearObjectStoreOperation):
* Modules/indexeddb/IDBTransactionBackend.h:

Make each operation’s perform() method defer to the IDBServerConnection (with a callback):
* Modules/indexeddb/IDBTransactionBackendOperations.cpp:
(WebCore::CreateObjectStoreOperation::perform):
(WebCore::CreateIndexOperation::perform):
(WebCore::CreateIndexAbortOperation::perform):
(WebCore::DeleteIndexOperation::perform):
(WebCore::DeleteIndexAbortOperation::perform):
(WebCore::GetOperation::perform):
(WebCore::PutOperation::perform):
(WebCore::SetIndexesReadyOperation::perform):
(WebCore::OpenCursorOperation::perform):
(WebCore::CountOperation::perform):
(WebCore::DeleteRangeOperation::perform):
(WebCore::ClearObjectStoreOperation::perform):
(WebCore::DeleteObjectStoreOperation::perform):
(WebCore::IDBDatabaseBackend::VersionChangeOperation::perform):
(WebCore::CreateObjectStoreAbortOperation::perform):

Add accessors to each operation’s data members so the IDBServerConnection has everything it needs:
* Modules/indexeddb/IDBTransactionBackendOperations.h:
(WebCore::CreateObjectStoreOperation::objectStoreMetadata):
(WebCore::DeleteObjectStoreOperation::objectStoreMetadata):

Implement each operation in terms of the appropriate backing store, then perform the callback:
