    * include/video.h, include/vlc_config.h, src/video_output/*: changed the
       picture buffer allocation scheme to allocate pictures from the render
       heap in a clockwise fashion instead of always picking the first available
       one from the start of the heap.
       This allows us to benefit from ffmpeg's macro-block skipping feature.
       As a side effect, we also have less chance of reusing a refrence picture
       buffer when we can't link/unlink them.
    
    * modules/codec/ffmpeg/video.c: modified the direct rendering code to benefit
       from the macro-block skipping algorithm.
       A new flag has also been introduced in the video_output's render heap to
       forbid modifications to the render picture buffers (for instance to overlay
       subtitles).
