All backends follow the same pattern of queueing events first in
ClutterMainContext, then copying them to a ClutterStage queue and
immediately free them. Instead, we can just pass ownership of events
directly to ClutterStage thus avoiding the allocation and copy in
between.

_clutter_stage_window_can_clip_redraws is used to check for clipped redraws
support but can_clip_redraws is not implemented by clutter-stage-wayland so
it always returns FALSE causing full screen redraws.
Fix that by implementing can_clip_redraws in clutter-stage-wayland.

When talking to other applications or serializing the modifier
state (and in particular when implementing a wayland compositor),
the effective modifier state alone is not sufficient, one needs
to know the base, latched and locked modifiers.
Previously one could do with backend specific functionality
such as clutter_device_manager_evdev_get_xkb_state(), but the
problem is that the internal data structures are updated as
soon as the events are fetched from the upstream source, but
the events are reported to the application some time later,
and thus the two can get out of sync.
This way, on the other hand, the information is cached in the
event, and provided to the application with the value that
was current when the event was generated.
https://bugzilla.gnome.org/show_bug.cgi?id=706494
All evdev devices are slave devices, which means that xkb state
and pointer position must be shared by emulating a core keyboard
and a core pointer. Also, we must make sure to add all modifier
state (keyboard and button) to our events.

This is necessary to avoid a deadlock with the compositor. When setting
a stage size before the stage was shown this would trigger a redraw
inside clutter_stage_wayland_resize. This redraw would result
in a call into eglSwapBuffers which would attach a buffer to the surface
and commit. Unfortunately this would happen before the role for the
surface was set. This would result in the compositor not relaying to the
client that the desired frame was shown.
With this change the call to wl_shell_surface_set_toplevel is always
made before the first redraw.

We should not create a shell surface and set the role for that shell
surface if the surface was a foreign one provided through
clutter_wayland_set_wl_surface
https://bugzilla.gnome.org/show_bug.cgi?id=699578
This adds support for optionally a providing a foreign Wayland surface
to a ClutterStage before it is first show. Setting a foreign surface
prevents Cogl from allocating a surface and shell surface for the stage
automatically.

This allows the integration of Clutter with another library, like GTK+,
that is dispatching the events itself. This is implemented by calling
into the cogl_wayland_renderer_set_event_dispatch_enabled() and since
that function must be called on the newly created renderer the newly
added clutter_wayland_disable_event_retrieval must be called before
clutter_init()

The Wayland 1.0 API allows orthoganal components of an application to
query the shell and compositor themselves by querying their own
wl_registry. The corresponding API in Cogl has been removed so Clutter
shouldn't call it anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=703878
The Wayland server API has changed so that wl_shm_buffer is no longer
a type of wl_buffer and wl_buffer will become an opaque type. This
changes ClutterWaylandSurface to accept resources for a wl_buffer
instead of directly taking the wl_buffer so that it can do different
things depending on whether the resource points to an SHM buffer or a
normal buffer. This matches similar changes to Cogl:
https://git.gnome.org/browse/cogl/commit/?id=9b35e1651ad0e46ed48989https://bugzilla.gnome.org/show_bug.cgi?id=703608
The majority of Clutter input events require a time so that that the
upper levels of abstraction can identify the ordering of events and also
work out a click count.
Although some Wayland events have microsecond timestamps not all those
that Clutter expects do have. Therefore we would need to create some
fake times for those events. Instead we always calculate our own time
using the monotonic time.
https://bugzilla.gnome.org/show_bug.cgi?id=697285
Cogl (as of 0b2b46ce) now only sets the shell surface as toplevel when
the CoglOnscreen is shown.
Without calling wl_shell_surface_set_toplevel the compositor will not
know what role to give to the compositor and thus the stage will not
appear.
When we look to support multiple roles / foreign surfaces we will need
to revisit this call and ensure we only call it when we are working in
the default case.
https://bugzilla.gnome.org/show_bug.cgi?id=703188
Since Cogl also polls on this file descriptor we can get into situations
where our event source is woken up to handle events but those events
have instead been handled by Cogl resulting in the source sitting in
poll().
We can safely rely on Cogl to handle the polling on the event source and
to dispatch those events.
https://bugzilla.gnome.org/show_bug.cgi?id=702202
On the other backends we will get some sort of expose event after
showing the stage's window which will queue a redraw. These expose
events don't exist on Wayland so nothing will cause Clutter to queue a
redraw. Weston doesn't bother displaying anything for the stage's
surface until the first buffer is sent, which of course it will never
receive if Clutter doesn't paint anything. This patch just makes it
explicitly queue a redraw after the stage is shown so that we will
always pass at least one frame to the compositor.
The bug can be seen by running test-stage-sizing. That example doesn't
have any animations so it won't try to queue any redraws until
something interacts with it. On the other hand something like
test-actors works fine without the patch because it constantly queues
redraws anyway in order to display the animation.

The definition of wl_display differs between Wayland clients and

Add support for repeating keys to the Wayland input backend.
Unfortunately the repeat delay/interval is hardcoded into the Clutter

For Wayland, this is mostly the input protocol having changed, although
there's also the SHM pool API, the cursor API, as well as fullscreen and
ping.
Also port to the new (months-old) xkbcommon API, as used by Weston 0.95.
This involves having xkbcommon manage the state for us, where
appropriate. Fans of multi-layout keyboards (or just caps lock) will no
doubt appreciate these changes.

Acquiring the Clutter lock to mark critical sections is not portable,
and not recommended to implement threaded applications with Clutter.
The recommended pattern is to use worker threads, and schedule UI
updates inside idle or timeout handlers within the main loop. We should
enforce this pattern by deprecating the threads_enter()/leave()
functions. For compatibility concerns, we need internal API to acquire
the main lock during frame processing dispatch.

This adds a virtual function to ClutterInputDevice to translate a
keycode from the hardware_keycode member of ClutterKeyEvent to an
evdev keycode. The function can fail so that input backends that don't
have a sensible way to translate to evdev keycodes can return FALSE.
There are implementations for evdev, wayland and X. The X
implementation assumes that the X server is using an evdev driver in
which case the hardware keycodes are the evdev codes plus 8.
