[cogl] onscreen: move swap_buffer apis to onscreen namespace

[Robert Bragg <rbragg src gnome org>]

commit 479c5fd2c965b79ca19986150b2bb36f0e595e00
Author: Robert Bragg <robert linux intel com>
Date:   Wed Feb 8 23:46:16 2012 +0000

    onscreen: move swap_buffer apis to onscreen namespace
    
    This moves all the cogl_framebuffer_ apis relating to swap buffer
    requests into the cogl_onscreen_ namespace since on CoglOnscreen
    framebuffers have back buffers that can be swapped.
