Make enum_params and set_param to configure properties, format and other parameters. This allows us to remove some duplicate code and make the properties and parameters much more extensible. Use the object id to mark the id of the parameter. Remove the spa_format and spa_props. We can now make the client-node easier by merging the various format methods into the params. Make the stream API more powerful now that we can pass params around.
