217790871e lavfi: issue error if maximum number of filters is reached
Issue an error and return a more meaningful error code in case the
maximum number of registered filters has been reached.
This is better than silently ignore the error, improve feedback.

71c644ceda lavfi: set link audio time_base if not set in avfilter_config_links()
The set value depends on the input link, or on the sample_rate value.
Avoids the need to explicitely set the time_base value.

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.

2c0317419b lavfi: simplify signature for avfilter_get_audio_buffer() and friends
The additional parameters were never used and are complicating the
function interface. Also, they were inconsistent with the way the
video API works.

So this assumes that a requested samples buffer will have *always* the
format specified in the requested link.

This breaks audio filtering API and ABI.

5f68a91be2 lavfi: remove default config_props() callback and refactor avfilter_config_links()
Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Also remove channel_layout check as it is now negotiated.

95a0242642 lavfi: prefer nb_samples over size in AVFilterBufferRefAudioProps
Remove AVFilterBufferRefAudioProps.size, and use nb_samples in
avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in
place of size.

This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
