Add extension support to modules. This is a list of extension commands that can be performed on the module. Remove the custom registry of extensions and make proper modules that implement the extensions. This is more in line with what pulseaudio does. The advantage is that the modules actually show up in the module list and that we can use the module user_data to implement the extension later.
