The source supports *planar* double, fix regression introduced by me in
4d4098da.

Fix crash.

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.

all known bugs in the interface code have been fixed

It's more convenient to have them all in one file.

This is easier to follow than having them randomly scattered in
avfilter.c and defaults.c.

Based on a patch by Mina Nagy Zaki <mnzaki@gmail.com>

It's the same as av_vsrc_buffer_add_frame(), except it doesn't take pts
or pixel_aspect parameters. Those are read from AVFrame.

Deprecate av_vsrc_buffer_add_frame().

Most of the code will be shared for both audio and video version.

avfilter.h is a public header and the unexported audio.h header contains
only internal prototypes.

Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

There is no real reason for it to be 64bit, it's just a plain int in the
rest of Libav.

There's no reason for it to be explicitly 32 bits. It's declared as a
plain int in all other places in Libav.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

The additional parameters are just complicating the function interface.

Assume that a requested samples buffer will *always* have the format
specified in the requested link.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place
everywhere.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

Also remove the useless planar parameter, which can be deduced from the
sample format.

This is technically an API and ABI break, but since the audio part of
lavfi is not usable now, this should not be a problem in practice.

This is similar to what has previously been done in AVFrame to allow
dealing with more than 8 channels.

Also add the public interface libavfilter/buffersink.h.

A nontrivial public function such as this should most certainly NOT be
inline.
