- Sync with latest B2 video_vosf.h updates.

- Enable VidMode extension with FBDev DGA graphics. - Factor out FBDev/XF86 DGA code. - Fix pointer grab in fbdev DGA mode, thus fixing scrolling screens in lower VidModes. - Only select VidModes that match the requested resolutions, exactly. - Fix VideoQuitFullScreen() in non FBDev mode.
