If a frame callback is destroyed before it is invoked then the struct
would be freed but it would not be removed from the array of callbacks
so when cogland later tried to emit the callback it would crash. This
patch instead stores the callbacks in a GQueue with embedded list
nodes so that they can be removed from the list in the resource
destructor. That way it doesn't matter how the resource is destroyed,
it will still get removed from the list.

Wayland has changed so that the shell interface now only has one
function which returns a shell surface for the surface. This patch
makes it create a dummy service in the same way that the wayland demo
compositor does. The implementation of the shell_surface_interface for
that dummy service is all no-ops.

This updates the cogland Wayland compositor example with is an extremely
minimal Wayland compositor. It demonstrates a multi(4)-head compositor
whereby client buffers are simply stretched to cover all outputs. No
input or shell features are implemented since it's really only for
demonstrating the use of Cogl.

This adds an example cogl compositor to test the
_cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4
output displays but doesn't support input since Cogl doesn't deal with
input. It's quite a minimal example of what it takes to write a wayland
compositor so could be interesting to anyone learning about wayland.
