vo_opengl: add infrastructure for hardware decoding OpenGL interop
Most hardware decoding APIs provide some OpenGL interop. This allows using vo_opengl, without having to read the video data back from GPU. This requires adding a backend for each hardware decoding API. (Each backend is an entry in gl_hwdec_vaglx[].) The backends expose video data as a set of OpenGL textures. Add infrastructure to support this. The next commit will add support for VA-API.
