Make video_buffer more generic

The video buffer took ownership of the producer frame (so that it could swap frames quickly). In order to support multiple sinks plugged to the decoder, the decoded frame must not be consumed by the display video buffer. Therefore, move the producer and consumer frames out of the video buffer, and use FFmpeg AVFrame refcounting to share ownership while avoiding copies.
