* ldn: Implement calls of UserLocalCommunicationService - Implement `IUserServiceCreator: CreateUserLocalCommunicationService` according to RE. - Implement `IUserLocalCommunicationService` calls: - Every calls in this interface are layered to `NetworkInterface`. - `GetState` according to RE. - `InitializeOld`, `Initialize` and `Finalize` stubbed with the appropriate result code and some TODO according to RE. - `AttachStateChangeEvent` according to RE. * Fix var name and TODO comments * Fix review
