Favor av_buffersrc_add_ref() instead, which is more powerful.

libavfilter API was designed in order to be clarly distinguished from the
libavcodec API, including avcodec.h in avfilter.h is not going to help to
stick to this principle.

The inclusion of libavutil/audioconvert.h in many files was required
because avcodec.h includes audioconvert.h.

libavfilter/avcodec.h is where the lavc/lavfi interface should be
entirely placed.

Most of the code is moved to buffersrc.c
to help Git see the similarities.

src_buffer.c still contains the obsolete compatibility functions.

The format change detection code was removed as it has been
implemented directly in ffmpeg.
It can easily be brought back from the history.

Some of the FATE changes are due to off-by-one different rounding being used
(lrintf vs av_rescale_q).
Some fate changes are due to 1 audio frame less being encoded (the new variant seems
matching what qatar does and according to ffprobe its closer to the requested duration)
the mapchan feature sadly is lost in this commit because it depends on resampling
being done in ffmpeg.c which is now moved completely into the av filter layer
-async is broken after this commit, this will be fixed in subsequent commits
the new filter reconfiguration system is flawed and will drop a frame on each
parameter change which is why the nelly moser checksums need updating.

It's the same as av_vsrc_buffer_add_frame(), except it doesn't take pts
or pixel_aspect parameters. Those are read from AVFrame.

Deprecate av_vsrc_buffer_add_frame().

Implement av_buffersrc_get_nb_failed_requests.
Deprecate av_vsrc_buffer_get_nb_failed_requests.

It is no longer used anywhere.

Furthermore, the header it was declared in was not installed,
so it can not be considered part of the public API.

av_buffersrc_add_ref can handle audio too now.

This function merges the features of
av_vsrc_buffer_add_video_buffer_ref() and
av_buffersrc_buffer().

It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a
memcpy.

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_".
