delta is in samples, not bytes. Also the sample format is not guaranteed
to be planar.

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.

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

Currently it will do padding, but it does not properly handle
start-of-stream trimming as documented.

The max_comp option is supposed to limit maximum compensation, but
currently the clipped value is not actually used.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

A number of compilers, for example those from TI and IBM, choke on
these initialisers. The current style is also quite ugly.

This is more consistent with what the rest of Libav does.
This breaks API.

Fixes an infinite loop on flush when avresample_get_delay() still
reports some samples but avresample_convert() doesn't return any data.

Double does not have enough precision to represent all int64 numbers
exactly.

This allows for padding/trimming at the start of stream. By default, no
assumption is made about the first frame's expected pts, so no padding or
trimming is done.

Make sure that an output frame has really been produced before returning
0.

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.

They are only useful inside filters and we don't allow user filters for
now.
