Options

* all: created a new module type "opengl provider", which provides a 

   simple interface to create and use OpenGL windows
 * modules/video_output/x11/glx.c: the GLX vout now implements the
  "opengl provider" interface
 * modules/visualization/galaktos/*: no more dependency on GLX: we use
   the generic opengl provider interface instead.
