Useful for examining options, the same as the corresponding functions
for the other libs.

Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

Also reorder some other #include when applicable.

libavfilter/avfilter.c:224:9: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 5 has type ‘int’ [-Wformat]

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

This is more consistent with naming in the rest of Libav.

This will allow making AVFilterPad opaque for the calling apps, since
those are the only two fields that can be useful to the users.

They are only useful inside filters and we don't allow user filters for
now.

Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Remove now empty defaults.c

This fixes a compilation failure with -DDEBUG.

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

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.

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.

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.

Based on a commit by Stefano Sabatini <stefano.sabatini-lala@poste.it>

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

avfilter_copy_frame_props() avoids code duplication and increases
robustness.

It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.
