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.
