We need to track the full xkb_state to have the necessary information
to send to the clients, otherwise they may get confused and lock
or invert the modifiers. In the evdev backend, we just retrieve the
same state object that clutter is using, while in the other backends
we fake the state using what clutter is providing (which is a subset
of what X11 provides, which would be necessary to have full state)

When running Mutter under Cogl's KMS backend no cursor will be
provided so instead this makes it so the cursor will be painted as a
CoglTexture that gets moved in response to mouse motion events. The
painting is done in a subclass of ClutterStage so that we can
guarantee that the cursor will be painted on top of everything else.
This patch adds support for the set_cursor method on the pointer
interface so that clients can change the cursor image.
The set_pointer method sets a surface and a hotspot position to use
for the cursor image. The surface's buffer is converted to a
CoglTexture and attached to a pipeline to paint directly via Cogl. If
a new buffer is attached to the surface the image will be updated. The
cursor reverts back to the default image whenever to the pointer focus
is moved off of any surface.
The image for the pointer is taken from X. It gets installed into
a fixed data location for mutter.
This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.
The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.
