This tool uses lavfi internal symbols not accessible in shared
libraries.  TESTPROGS are linked statically to allow them use of
library internals not normally exported.

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

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.

This is required for extending lavfi tests to audio filtering.

Use av_get_pix_fmt_name() rather than access
av_pix_fmt_descriptors. Improve readability.

The new name is shorter and more consistent with the FFmpeg API, and
sounds less evil.

AVFilterContext *avfilter_open(AVFilter *filter, const char *inst_name);
to:
int avfilter_open(AVFilterContext **filter_ctx, AVFilter *filter, const char *inst_name);

This way it is possible to propagate an error code telling the reason
of the failure.

target regtest-lavfi_pix_fmts.

The lavfi_pix_fmts test is disabled, this because there are
many tests which are failing, and there are still some output files
which cannot be played by NUT/ffplay.
