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.

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.

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.

also update the multiple inclusion guards in config.h|mak

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

dprintf clashes with POSIX.1-2008

This removes ff_get_ref_perms_string, ff_dprintf_ref and ff_dprintf_link

rather than always use AV_TIME_BASE_Q.

This fixes configuration for all the filters which do not use the
default config_props for the output link, and do not set explicitely
the timebase.
