Anton Khirnov a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init()
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.

Anton Khirnov 9baeff9506 lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs

Anton Khirnov 84b9fbe055 lavfi: add avfilter_pad_get_type() and avfilter_pad_get_name().
This will allow making AVFilterPad opaque for the calling apps, since
those are the only two fields that can be useful to the users.

Mina Nagy Zaki 88c3b87bd8 lavfi: deprecate 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.

Remove now empty defaults.c

Anton Khirnov 472fb3bbfa lavfi: remove some audio-related function from public API.
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

Stefano Sabatini 7ef0adcc2e lavfi: simplify signature for avfilter_get_audio_buffer() and friends
The additional parameters are just complicating the function interface.

Assume that a requested samples buffer will *always* have the format
specified in the requested link.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

Stefano Sabatini e727bca392 lavfi: cleanup avfilter_get_audio_buffer() and pals.
Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place
everywhere.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

Also remove the useless planar parameter, which can be deduced from the
sample format.

This is technically an API and ABI break, but since the audio part of
lavfi is not usable now, this should not be a problem in practice.

Mans Rullgard cc276c85d1 Make channel layout masks unsigned
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.

Reinhard Tartler 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.
