* 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.
