This merged gtk, gdk and gsk into one library, making it possible to
have internal private APIs between gtk them, as well as producing more
efficient code.

These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.
This commit changes the way GskRenderer and GskRenderNode interact and
are meant to be used.
GskRenderNode should represent a transient tree of rendering nodes,
which are submitted to the GskRenderer at render time; this allows the
renderer to take ownership of the render tree. Once the toolkit and
application code have finished assembling it, the render tree ownership
is transferred to the renderer.
GSK is conceptually split into two scene graphs:
* a simple rendering tree of operations
* a complex set of logical layers
The latter is built on the former, and adds convenience and high level
API for application developers.
The lower layer, though, is what gets transformed into the rendering
pipeline, as it's simple and thus can be transformed into appropriate
rendering commands with minimal state changes.
The lower layer is also suitable for reuse from more complex higher
layers, like the CSS machinery in GTK, without necessarily port those
layers to the GSK high level API.
This lower layer is based on GskRenderNode instances, which represent
the tree of rendering operations; and a GskRenderer instance, which
takes the render nodes and submits them (after potentially reordering
and transforming them to a more appropriate representation) to the
underlying graphic system.
Quite a few applications use GTK_WINDOW_POPUP to create various
temporary windows and place then on screen. That works fine on X11 but
on Wayland there is no global coordinate system for regular surfaces.
If the application is using a gdk temp window and set a parent with
gtk_window_transient_for(), the gdk wayland backend has all it needs to
create a subsurface that can be placed at will by the application.

Places sidebar shows XDG directories, mounted and unmounted devices,
connected networks, bookmarks and actions like 'Connect to server'
and 'Insert location', which causes the sidebar to grow very quickly
and look cluttered. Because of that, new mockups for the sidebar try
to simplify it.
To make the sidebar simpler, the new mockups propose that it should
only handle connected networks and removable devices such as flash
drives and USB devices, and delegates other devices for external
widgets through the 'Other Locations' item.
To handle fixed devices and manage network connections, add a new
widget named GtkPlacesView, based on Nautilus mockups to keep
consistency between GNOME file management tools - in this case,
between Nautilus and the bundled Gtk's file chooser.

This is just meant as a prototype for how we can show a
scroll position indicator for touch. This uses GTK_POLICY_EXTERNAL
to hide the scrolled windows scrollbar while still allowing
scrolling.
This signal is emitted whenever user scrolling hits the overshoot
edge in the given direction. May be useful to add "reload" or "load
more" behaviors in apps.

This shows what one currently has to do manually to get the typical
selection mode with blue headerbar and checkboxes in list rows.
The goal is to make this easier.
