    Bug 676150 GDK: Fix build on Windows
    
    -Don't include unistd.h and stdint.h unconditionally as not all Windows
     compilers have them around.
    -Only include cogl/cogl-xlib.h when it is really supported by Cogl and GDK.
    -sys/ioctl.h is not available on Windows (MinGW/MSVC).
    -Correct the call to cogl_renderer_set_winsys_id:
     (backend_cogl->cogl_renderer, COGL_WINSYS_ID_WGL) ->
     (renderer, COGL_WINSYS_ID_WGL)
