It is unused since 02aa0701ae.
The corresponding size field is write-only since then.

They have been deprecated in 61097535cd,
yet this was less than two years ago. Removing them will therefore have
to wait.

The channel_layouts and channel_counts options set what buffersink
is supposed to accept. If channel_counts contains 2, then stereo is
already accepted, there is no point in having it in channel_layouts
too. This was not properly documented until now, so only print a
warning.
A lot of changes happen at the same time:
- Add a framequeue fifo to AVFilterLink.
- split AVFilterLink.status into status_in and status_out: requires
changes to the few filters and programs that use it directly
(f_interleave, split, filtfmts).
- Add a field ready to AVFilterContext, marking when the filter is ready
and its activation priority.
- Add flags to mark blocked links.
- Change ff_filter_frame() to enqueue the frame.
- Change all filtering functions to update the ready field and the
blocked flags.
- Update ff_filter_graph_run_once() to use the ready field.
- buffersrc: always push the frame immediately.
Instead of calling the input filter request_frame() method,
ff_request_frame() now marks the link and returns immediately.
buffersink is changed to activate the marked filters until
a frame is obtained.
The status field can carry any error code instead of just EOF.
Also only update it through a wrapper function and provide a timestamp.
Update the few filters that used it directly.
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.
All of these were found by using av_warn_unused_result, demonstrating its utility.
Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.
Fixes: CID 1325680, 1325679, 1325678.

Do not assume that ff_request_frame() returning success
implies a frame has arrived in the FIFO.
Instead, just loop until a frame is in the FIFO.
It does not change anything since the same loop is present
in ff_request_frame(), confirmed by an assertion.
Use sizeof(void *) as its value, because AVFilterBufferRef is deprecated.

Previously it was partly only added to central functions called
internally, however if GCC would inline these into the public fuction, the
alignment attribute would not take effect.
Instead, add it to all public entry points to avoid these problems.

The functions which actually drive the filter graph by pushing
frames through it need to ensure an aligned stack for SIMD functions.

the cost of more diff.
