[gtk+/wip/matthiasc/gdk-settings: 1/12] gdk: Add settings api to GdkDisplay

    gdk: Add settings api to GdkDisplay
    
    This commit adds gdk_display_get_setting and a ::setting-changed
    signal, which will replace the settings event we use now. Note
    that I've done away with the GdkSettingAction argument that the
    event has, since we are not using it at all.
