* clutter/cogl/gl/cogl.c: (cogl_check_extension):
Actually populate this func and remove the static alternate
named one. Means GLX actually checks for available extensions.
Other minor tidy ups.
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-backend-glx.h:
Add support for GLX_SGI_swap_control to do vblanking prefering
over glXGetVideoSyncSGI. Should fix issues on Intel chips with
very slow frame rates due to vblank problems.
Thanks to Michel Danzer for tips, see;

* test/test-actors.c:
Change FPS to 60.
