* ffmpeg update to 51.28.0

  * Workaround ffmpeg buggy codecs that don't release their DR1 frames.
  * Fix several segfaults and freezing problem with H264 streams that use a lot
    of reference frames (eg. 15)
  * Initial support to enable/disable ffmpeg codecs. Codecs may be disabled in
    groups by --disable-ffmpeg-uncommon-codecs/--disable-ffmpeg-popular-codecs
    Think of "uncommon" codecs what people would never want to play with their
    PDAs (they will save memory by removing them).
    Note: currently both uncommon/popular codecs are _build_ but disabled.
    that is, build system still need some improvements to really save memory.
warning: non-autoconf guru playing with the build system, likely breakage.
