lavfi: switch ff_default_get_audio_buffer() to av_frame_get_buffer()
...
This simplifies the code and avoids using libavcodec-specific
avcodec_fill_audio_frame().

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

lavfi: merge start_frame/draw_slice/end_frame
...
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

Include libavutil/channel_layout.h instead of libavutil/audioconvert.h
...
Also reorder some other #include when applicable.

lavfi/audio: eliminate ff_default_filter_samples().
...
It currently does the following:
1) get a zeroed audio buffer
2) copy some properties (but not the data) of the input buffer to it
3) pass this buffer to the output filter
This looks useless and is indeed not used by any filters, therefore
delete it.
Make ff_null_filter_samples() (just pass the buffer to the next filter)
the new default.

lavfi/audio: don't set cur_buf in ff_filter_samples().
...
It's redundant, since the input buffer is passed as a parameter to the
filter_samples() callback, and can lead to stale pointers remaining on
the link.

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

lavfi: move audio-related functions to a separate file.

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