‘sincos’ is a GNU extension. cogl-gles2-gears was using it without
defining _GNU_SOURCE so it was generating some annoying warnings. This
patch fixes it by making the example include config.h which will end
up defining _GNU_SOURCE.
In addition this patch adds a configure check for the function and
provides a fallback if it's not available.

The first vertex in the triangle vertices used in the cogl-hello
example (which were copied into a few other examples) for some reason
has a semi-transparent alpha component. However the colour needs to be
pre-multiplied and the red component was still 0xff so the colour is
effectively invalid and the transparency isn't shown. This patch just
sets the alpha component to 0xff to make it less confusing.

Cogland works a lot better with an EGL context because then Mesa will
automatically set up the wl_drm object and it can accept DRM buffers.
However Cogland is still useful with GLX because it can gracefully
fallback to accepting only SHM buffers. This patch therefore makes it
first try creating and connecting a renderer with the EGL constraint,
but if that doesn't work it will try again without it.

When a Wayland compositor gets a commit it only needs to redraw the
region specified by the pending damage event. Previously Cogland was
ignoring damage events for non-shm buffers and just always queuing a
redraw after a commit event. This patch changes it to queue a redraw
only in response to a damage event. In practice this doesn't really
make much difference because Cogland doesn't do anything clever to
handle updating a sub-region of the screen, but it more costly matches
the model a compositor should use.

If the shell surface is requested twice then Cogland will hit an error
path but it would end up leaking the CoglandShellSurface struct it
allocated.

The handler for the destroy signal on the pending buffer was not
correctly being removed if the same buffer is committed twice to the
surface. It was also not being cleared if the surface is destroyed
before the pending buffer is committed.

This essentially just moves install_corners() from the compositor, through
the core, into the UI layer where it arguably should have been anyway,
leaving behind stub functions which call through the various layers. This
removes the compositor's special knowledge of how rounded corners work,
replacing it with "ask the UI for an alpha mask".
The computation of border widths and heights changes a bit, because the
width and height used in install_corners() are the
meta_window_get_outer_rect() (which includes the visible borders but not
the invisible ones), whereas the more readily-available rectangle is the
MetaFrame.rect (which includes both). Computing the same width and height
as meta_window_get_outer_rect() involves compensating for the invisible
borders, but the UI layer is the authority on those anyway, so it seems
clearer to have it do the calculations from scratch.

XUngrabKey() doesn't work for XI2 grabs and XI2 doesn't provide API
with similar functionality. As such, we have to refactor the code a
bit to be able to call XIUngrabKeycode() for each key binding, then
reload keybindings and finally grab the new ones.

We want to avoid clutter-x11.h leaking Clutter symbols (i.e. you need to
include clutter.h yourself before including clutter-x11.h), but we need
to do so conditionally, so that ancillary stuff like gtk-doc and
g-ir-scanner get the right types while building Clutter itself.
