/** \class wl_listener
*
* \brief A single listener for Wayland signals
*
* wl_listener provides the means to listen for wl_signal notifications. Many
* Wayland objects use wl_listener for notification of significant events like
* object destruction.
*
* Clients should create wl_listener objects manually and can register them as
* listeners to signals using #wl_signal_add, assuming the signal is
* directly accessible. For opaque structs like wl_event_loop, adding a
* listener should be done through provided accessor methods. A listener can
* only listen to one signal at a time.
*
* ~~~
* struct wl_listener your_listener;
*
* your_listener.notify = your_callback_method;
*
* \comment{Direct access}
* wl_signal_add(&some_object->destroy_signal, &your_listener);
*
* \comment{Accessor access}
* wl_event_loop *loop = ...;
* wl_event_loop_add_destroy_listener(loop, &your_listener);
* ~~~
*
* If the listener is part of a larger struct, #wl_container_of can be used
* to retrieve a pointer to it:
*
* \code
* void your_listener(struct wl_listener *listener, void *data)
* {
* struct your_data *data = NULL;
*
* your_data = wl_container_of(listener, data, your_member_name);
* }
* \endcode
*
* If you need to remove a listener from a signal, use #wl_list_remove.
*
* \code
* wl_list_remove(&your_listener.link);
* \endcode
*
* \sa wl_signal

* using #wl_signal_emit, which will invoke all listeners until that
