Move xdg_shell related functionality to a new meta-wayland-xdg-shell.c
and wl_shell related functionality to a new meta-wayland-wl-shell.c,
and adapt role object tree.
Common functionality related to the surface being drawn as a
MetaSurfaceActor was moved to a MetaWaylandSurfaceRoleActorSurface role.
The subsurface role GObject is made to inherit the actor surface GObject.
Shell surface hooks (configure, ping, close, popup done) were added to
a MetaWaylandSurfaceRoleShellSurface GObject which inherits the
surface actor role GObject.
The shell surface roles (xdg_surface, xdg_popup, wl_shell_surface) are
made to inherit the shell surface GObject and implement the relevant
API.

Clutter out of tree depends on Cogl's required dependencies via the
pkg-config file. Since Clutter and Cogl moved in tree, it means that
those dependencies need to be checked by Clutter itself, otherwise
headers and libraries won't be found.
Leave these checks up to the callers, the only uses of this function
(indirect, through meta_wayland_seat_get_grab_info) are
[wl_shell|xdg]_surface.move/resize/show_window_menu.
In move/resize it makes sense to check for a button being pressed, because
we must expect a button release event. However for xdg_surface.show_window_menu
we 1) don't strictly need further events and 2) we must account for press+release
event pairs being processed at once in the compositor before the client sees
the former.
That is eg. the case of touchpad 2nd/3rd button tap emulation, multifinger
taps will emit the event pair at once, so when the client manages to request
xdg_surface.show_window_menu, it'll be too late in the compositor side, so the
request is ignored.

A wl_data_device object may be created while it is being focused,
either because the client destroyed it or because the client was
destroyed. Handle this by early out in focus handler vfuncs the case
where it was destroyed, so that we don't corrupt memory and/or cause
segmentation fault.

Wrap the existing laptop_display_is_on() method in a public function
that gnome-shell can use to query whether a builtin output is present
and enabled.

If we get a key event but still have pending modifier state changes we
need to send a modifiers event right away so that the key event can be
interpreted by clients correctly modified.
This case could happen when mutter/gnome-shell itself consumes the
modifier key press event such as with the overview key which by
default is triggered on super press.

The wayland protocol has enough space to send both virtual and real
modifiers on modifiers events which saves clients the work of
resolving virtual modifiers themselves.

While CoglError is a define to GError, it doesn't follow the convention
of ignoring errors when NULL is passed, but rather treats the error as
fatal :-(
That's clearly unwanted for a compositor, so make sure to always pass
an error parameter where a runtime error is possible (i.e. any CoglError
that is not a malformed blend string).
