Instead of setting multiple callbacks, just let the user set one vtable with callbacks. Usually, GObject would implement this via signals. While that makes sense for public objects, for example to work better with GIR and allow intercepting the signal, this is overkill for our internal type. And NMPolkitListener already did not make use of signals, for good reason. Instead of passing multiple callbacks, must pass one structure with callback pointers. Also, extend the signature of the callbacks to always contain a @self argument and a @user_data.
