backends/native: Add input thread inside MetaSeatImpl

This (now) doesn't change anything in regards to the API that the UI
thread should access from the MetaSeatImpl. The MetaInputDeviceNative,
MetaInputSettings and MetaKeymap objects are now considered owned by
the input thread, as well as all of libinput objects.

The MetaEventSource now dispatches events in a GMainContext that is
the thread default to this thread, and all UI-thread-accessible API
(seat and virtual input device API) will be handled in a serialized
manner by that same input thread.

The MetaSeatImpl itself is still considered to be owned by the caller
thread, and all the signals that this object emits will be emitted in
the GMainContext that is default at the time of calling
meta_seat_impl_new().

The MetaInputSettings configuration changes will likewise be handled
in the input thread, close to libinput devices.

  * @short_description: Interface for animatable classes

  * #ClutterAnimatable is an interface that allows a #GObject class
- * to control how a #ClutterAnimation will animate a property.
+ * to control how an actor will animate a property.
  *
  * Each #ClutterAnimatable should implement the
  * #ClutterAnimatableInterface.interpolate_property() virtual function of the
  * interface to compute the animation state between two values of an interval
  * depending on a progress factor, expressed as a floating point value.
  *
- * If a #ClutterAnimatable is animated by a #ClutterAnimation
- * instance, the #ClutterAnimation will call
- * clutter_animatable_interpolate_property() passing the name of the
- * currently animated property; the values interval; and the progress factor.
- * The #ClutterAnimatable implementation should return the computed value for
- * the animated
- * property.

-/**
- * SECTION:clutter-drop-action
- * @Title: ClutterDropAction
- * @short_description: An action for drop targets
- *
- * #ClutterDropAction is a #ClutterAction that allows a #ClutterActor
- * implementation to control what happens when an actor dragged using
- * a #ClutterDragAction crosses the target area or when a dragged actor
- * is released (or "dropped") on the target area.
- *
- * A trivial use of #ClutterDropAction consists in connecting to the
- * #ClutterDropAction::drop signal and handling the drop from there,
- * for instance:
- *
- * |[<!-- language="C" -->
- *   ClutterAction *action = clutter_drop_action ();
- *
- *   g_signal_connect (action, "drop", G_CALLBACK (on_drop), NULL);
- *   clutter_actor_add_action (an_actor, action);
- * ]|
- *
- * The #ClutterDropAction::can-drop can be used to control whether the
- * #ClutterDropAction::drop signal is going to be emitted; returning %FALSE
- * from a handler connected to the #ClutterDropAction::can-drop signal will
- * cause the #ClutterDropAction::drop signal to be skipped when the input
- * device button is released.
- *
- * It's important to note that #ClutterDropAction will only work with
- * actors dragged using #ClutterDragAction.
- *
- * See [drop-action.c](https://git.gnome.org/browse/clutter/tree/examples/drop-action.c?h=clutter-1.18)
- * for an example of how to use #ClutterDropAction.
- *
- * #ClutterDropAction is available since Clutter 1.8

- * native motion notification into a Clutter #ClutterMotionEvent and ask
- * Clutter to process it:
- *
- * |[

- *
- *   translate_native_event_to_clutter (native_event, &c_event);
- *
- *   clutter_do_event (&c_event);
- * ]|

- * Before letting clutter_do_event() process the event, it is necessary to call
- * clutter_input_device_update_from_event():
- *
- * |[
- *   ClutterEvent c_event;
- *   ClutterDeviceManager *manager;
- *   ClutterInputDevice *device;

- *
- *   // use the default Core Pointer that Clutter backends register by default
- *   device = clutter_seat_get_pointer (seat);
- *
- *   // update the state of the input device
- *   clutter_input_device_update_from_event (device, &c_event, FALSE);
- *
- *   clutter_do_event (&c_event);
- * ]|
- *
- * The @update_stage boolean argument should be used when the input device
