no testcase available, just found this issue by reading the code

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.

This fixes a crash in YADIF filter when using a mingw build in a MSVC
application.

it should be updated

They are no longer needed since there is no incompatible
ABI version.

Reduce the diff with the fork.

Also apply a few cosmetic fixes (spaces, trailing comma) to
help match them with the fork's implementation.

Note: the implementation could be more efficient, but at
the cost of more diff.

Most of the code from the following commit:

    lavfi: add an audio buffer sink.

Adapted to call av_buffersink_get_frame_flags() instead of
accessing the frame directly.

Note: av_buffersink_get_samples() is not yet implemented,
abuffersink is not yet a drop-in replacement of the fork's
abuffersink.

Allow to select sample rates.

Add a field to the AVBufferSinkParams for a list of accepted
channel counts.
Change the default value for the lists in AVBufferSinkParams
to NULL, to let lavfi fill them with something useful.
The fail_enomem path is unneeded because filters are uninited
on failure.

This is following 568c70e79e.

Implement av_buffersink_read() and av_buffersink_read_samples()
for ffmpeg's version of buffersink.

With this change, avconv linked against ffmpeg's libraries passes
the same number of tests whether it uses ffbuffersink or
buffersink_old.

They are part of the public API. Their libav compatibility
counterpart are already enabled unconditionally.

Fix programmatic selection of accepted pixel formats.

With this change avconv compiled against libav and linked to ffmpegs libs
will run through the whole fate testsuite without any crashes.
857 tests pass, the remaining tests fail one way or another, which is
to be expected as avconv is not a drop in replacement for ffmpeg
The testsuite used was the ffmpeg fate testsuite, not libavs.

Use the init_opaque callback for the purpose.

Fix regression introduced in a5e8c41c28. In particular, fix lavfi
device in case a conversion to the supported (packed) formats is needed.

The file contains the code for the audio buffersink as well.

It was deprecated since a long time and removed after the 2->3 major
bump.
