Add FreeBSD native VGL driver. Right now it is work in progress and to activate

and test it you need the following (5-CURRENT only, BTW):
- fetch a patch for libvgl: http://people.freebsd.org/~sobomax/libvgl.patch,
  apply it, recompile/reinstall libvgl;
- recompile/reinstall sdl-devel (configure script automatically detects
  if right version of libvgl is present);
- set environment variable SDL_VIDEODRIVER=vgl;
- ensure that you have VESA support compiled into kernel or loaded as a kld;
- fire up your favourite SDL app ;).
