Bug#658084: libav-extra: Really necessary?

[Andres Mejia]

Ok, here are the changes to libav to include libav-extra so far. Just
tested these and they provide a smooth upgrade with libav/libav-extra
packages currently in unstable. avconv can use either libavcodec or
libavcodec-extra package and it works like it should. None of the
other packages were necessary as far as I can tell. Also, libav-source
will be dropped.

If nobody has any other suggestions, I would like to upload this to
experimental for further testing.
