[cogl/wip/runtime-egl-platform: 12/12] Move the EGL GDL winsys out of cogl-winsys-egl

commit 9716149a109b1f5722207b58fdb28fc7575f7660
Author: Neil Roberts <neil linux intel com>
Date:   Tue Dec 13 11:42:42 2011 +0000

    Move the EGL GDL winsys out of cogl-winsys-egl
    
    This moves all of the code specific to the gdl winsys out of
    cogl-winsys-egl. It is completely untested apart from that it
    compiles.
