The macro can be used to define consistently the internal class of a
filter, save some typing and factorize.

This breaks libavfilter ABI.

This is more consistent with naming in the rest of Libav.

It will allow adding new fields to it without ABI breaks.

The enabling symbol is renamed FF_AVFILTER_TRACE. Avoid conflicts with
the DEBUG macro, which may be defined for different purposes.

Its only used through the start_frame pointer and thus cannot be inlined easily.
It also appears to break compilation with some unidentified compiler on darwin.

These utilities are meant to be defined in avfilter.c, since they are
generic and thus contain both audio and video code.

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

The planar/packed switch and the packing_formats list is no longer
required, since the planar/packed information is now stored in the sample
format enum.

This is technically a major API break, possibly it should be not too
painful as we marked the audio filtering API as unstable.

This is easier to follow than having them randomly scattered in
avfilter.c and defaults.c.

Also add internal function ff_null_start_frame_keep_ref().

Fix crash when a following filter (e.g. settb) will unref the reference
passed by start_frame(), and then the reference is accessed in
end_frame() through inlink->cur_buf.

Keep a heap of all sink links ordered by timestamps.

This should fix a memleak.

A list of formats may have been dynamically created by the calling code,
and thus should not be referenced by the sink buffer context.

Avoid possible invalid data reference.

Also consistent with AVCodecContext.sample_rate. Simplify/avoid
pointless type checks and conversions.

Breaks audio API/ABI.

Reduce code duplication.

Also generalize it, making it accept ints rather than pixel formats.
Allow factorization.

Adopt K&R style for overall consistency/readability.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.

The function is going to be used to represent also audio data.

The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
