vdpau: add a postprocessing pseudo-filter
This factors out some code from vo_vdpau.c, especially deinterlacing handling. The intention is to use this for vo_vdpau.c to make the logic significantly easier, and to use it for vo_opengl (gl_hwdec_vdpau.c) to allow selecting deinterlace and postprocessing modes. As of this commit, the filter actually does nothing, since both vo_vdpau and vo_opengl treat the generated images as normal vdpau images. This will change in the following commits.
