The corresponding codec options (skip_loop, skip_idct, skip_frame) can be
set in a more flexible way.
This technically causes a user interface break, but since the options
were not even documented and we just released a major version that should
not be a serious issue.
Move non-obsolete functions, structures and constants outside
the scope of "#if FF_API_AVFILTERBUFFER".
Add attribute_deprecated to av_buffersink_get_buffer_ref()
and av_buffersink_poll_frame().
Add doxygen for av_buffersink_get_frame_flags().
* cus/stable:
ffplay: add -af option
ffplay: use refcounted frames for audio
ffplay: use frame->pts if available for setting the audio clock
ffplay: restructure audio stream opening code

The padding was lost during porting from avcodec
Should fix out of array accesses

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.

These smaller samples do not need to be unpacked to double words
allowing the code to process more pixels every iteration (still 2 in MMX
but 6 in SSE2). It also avoids emulating the missing double word
instructions on older instruction sets.
Like with the previous code for 16-bit samples this has been tested on
an Athlon64 and a Core2Quad.
Athlon64:
1809275 decicycles in C, 32718 runs, 50 skips
911675 decicycles in mmx, 32727 runs, 41 skips, 2.0x faster
495284 decicycles in sse2, 32747 runs, 21 skips, 3.7x faster
Core2Quad:
921363 decicycles in C, 32756 runs, 12 skips
486537 decicycles in mmx, 32764 runs, 4 skips, 1.9x faster
293296 decicycles in sse2, 32759 runs, 9 skips, 3.1x faster
284910 decicycles in ssse3, 32759 runs, 9 skips, 3.2x faster

This is a fairly dumb copy of the assembly for 8-bit samples but it
works and produces identical output to the C version. The options have
been tested on an Athlon64 and a Core2Quad.
Athlon64:
1810385 decicycles in C, 32726 runs, 42 skips
1080744 decicycles in mmx, 32744 runs, 24 skips, 1.7x faster
818315 decicycles in sse2, 32735 runs, 33 skips, 2.2x faster
Core2Quad:
924025 decicycles in C, 32750 runs, 18 skips
623995 decicycles in mmx, 32767 runs, 1 skips, 1.5x faster
406223 decicycles in sse2, 32764 runs, 4 skips, 2.3x faster
387842 decicycles in ssse3, 32767 runs, 1 skips, 2.4x faster
307726 decicycles in sse4, 32763 runs, 5 skips, 3.0x faster

Since lavfi works natively with AVFrame now, these functions are no longer
necessary and can be removed in a future bump.
