Don't use special callback in node to receive the results. Instead, use a generic result callback to receive the result. This makes things a bit more symetric and generic again because then you can choose how to match the result to the request and you have a generic way to handle both the sync and async case. We can then also remove the wait method. This also makes the remote interface and spa interface to objects very similar. Make a helper object to receive and dispatch results. Use this in the helper for enum_params. Make device use the same result callbacks.
