Before the change, filter_frame() always waited for 2 samples in the
bottom frames queue. This notably fixes commands such as
./ffplay tests/lena.pnm -vf split,blend=c0_mode=addition
This patch improves af_asyncts behavior on streams with bogus PTS, which
are either non-monotonic, or contain PTS jitter, and trigger the
non-monotonicity error. With this patch, af_asyncts is able to correct
these streams and avoid the error.
Firstly, it fixes resample compensation calculation by supplying proper
units to avresample_set_compensation (sample count per second instead
of sample count per some arbitrary frame size). Also, the calculation of
the compensation itself is fixed - delta is proportional to an adjustment
of the compensation, not the compensation itself. Ideally, the compensation
should converge to a value that keeps delta at zero.
To be able to deal with sources with PTS jitter even without resampling,
small PTS errors are adjusted, so the output frames do not overlap.
Finally, one more monotonicity check is added.
The FATE reference changes because now there is 8 less samples of
silence because of the pts jitter.

Inside send_silence(), delta_ts was used inconsistently:
sometimes as the new value, sometimes as the old value.
Consistently use it as the new value, and add an argument
to know the last segment duration.

lavc, lavfi: fix counting number of planes in AVBufferRef wrappers
Merged-by: Michael Niedermayer <michaelni@gmx.at>
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.
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().
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.
