As camera object have the potential to outlive the hardware they represent, there is a need to inform the camera that the underlying device has been disconnected, and in turn to notify applications. Implement a disconnection notification mechanism that can be used by pipeline handlers to notify the camera of disconnection. The camera then block all new API calls and emit the disconnected signal.
