Add an async result code and an event to signal the completion. Use async return values to signal completion of a method and potential state change. Add selected format to port update message. Make it possible to parse into a custom copy of the command memory. Remove state change events from the elements, we now just update the state. Implement async results in the proxy element Add support for removing buffers in the client. Fix up pinossink Deal with async return in the links.
