6b55aab01a lavfi: create buffer reference in filters which need to access the ref later
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.

386aee6864 sink_buffer: copy list of provided formats in the context
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.

4381bddc9f lavfi: consistently use int for sample_rate in AVFilterLink and AVFilterBufferRefAudioProps
Also consistent with AVCodecContext.sample_rate. Simplify/avoid
pointless type checks and conversions.

Breaks audio API/ABI.

4723bc2868 Make avfilter_default_free_buffer() an internal shared symbol, so that
it can be referenced outside defaults.c.

4fcbb2af33 Prefix with "ff_" the functions:
ff_avfilter_graph_check_validity()
ff_avfilter_graph_config_links()
ff_avfilter_graph_config_formats()

and move their declaration to internal.h. These functions are never
used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.

ecc8dada37 Rename AVFilterPicRef to AVFilterBufferRef.
The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.
