5a6c7a218c doc: merge libavfilter.texi into filters.texi
There is no much point into splitting documentation for filters. Also
having a separate document for a library is inconsistent.

4d4098da00 lavfi: drop planar/packed negotiation support
The planar/packed switch and the packing_formats list is no longer
required, since the planar/packed information is now stored in the sample
format enum.

This is technically a major API break, possibly it should be not too
painful as we marked the audio filtering API as unstable.
