Since Xlib.h is such a terrible citizen when it comes to symbol
namespacing it's not desirable to include Xlib.h if it is not absolutely
required. Cogl now has a standalone cogl-xlib.h that should be included
whenever any xlib specific symbols are required.
This patch updates clutter to include <cogl/cogl-xlib.h> wherever
clutter needs to use xlib specific cogl apis.

The g_atexit() function has been deprecated in GLib as it is a fairly
bad idea in basically all cases.
We could probably use a GCC destructor if we didn't care about
portability, but for the time being we just remove the atexit() handler
that disposed the backend.
Cogl changed has changed the name of cogl_context_egl_get_egl_context to
cogl_egl_context_get_egl_context to be consistent with other platform
specific symbols.
cogl_renderer_xlib_set_foreign_display was renamed to
cogl_xlib_renderer_set_foriegn_display so this is the corresponding
change to clutter.

Since GLX and EGL are abstracted by Cogl the two backends are both
implementing everything using the Cogl API and they are almost
identical.
This updates the egl backend to support everything that the glx backend
supports. Now that EGL and GLX are abstracted by Cogl, the plan is that
we will squash the clutter-egl/glx backends into one. Since the EGL
backend in clutter can conditionally not depend on X11 we will use the
EGL backend as the starting point of our common backend.
