[FFmpeg-devel] [RFC] Simplify avfilter_get_audio_buffer()

this is meant to simplify the signature and make it consistent with
the video API.

The only code using the feature is af_aconvert.c (not yet committed):

    if (aconvert->convert_chlayout) {
        aconvert->mix_samplesref =
                                      AV_PERM_WRITE | AV_PERM_REUSE2,

in this case it is requested a buffer with "formats" different from
the ones specified in the output link.

This code can be replaced by a combination of av_samples_alloc() and
avfilter_get_audio_buffer_ref_from_arrays() (which we may eventually
merge in a avfilter_alloc_audio_buffer() function).

This change is going to break ABI/API, so I'd commit it in the
instability period 1-month timeframe just after the next incoming
major bump (which I need for the sink API unification).

Anyone against?
