20c86571cc lavfi: let gcc realign the stack on public graph driving functions
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.

Vertical shift is log2_chroma_h, not log2_chroma_w.

c977039e58 lavc, lavfi: fix counting number of planes in AVBufferRef wrappers
Number of planes is not always equal to the number of components even
for formats marked with PIX_FMT_PLANAR -- e.g. NV12 has three components
in two planes.

6552808014 lavc,lavfi: fix calculating the plane size in the AVBufferRef wrappers
It is supposed to be height * linesize, not width * linesize.
Thanks to Hendrik Leppkes for pointing out the bug.

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

565e4993c6 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.

a903f8f087 Include libavutil/channel_layout.h instead of libavutil/audioconvert.h
Also reorder some other #include when applicable.

568c70e79e lavfi: convert input/ouput list compound literals to named objects
A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init()
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.
