Specifying --enable-static --disable-shared isn't necessary, these
are the defaults.

The list type was changed to int64_t to be able to hold
channel layouts.

avfilter_make_format_list() still takes a int32_t array and converts
it to int64_t. A new function, avfilter_make_format64_list, that
takes int64_t arrays has been added.

Also add the public interface libavfilter/vsink_buffer.h.

This filter is a simple wrapper around the LUT filter.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Make it returns the list of open inputs and outputs, so it can be
reused by applications.

Breaks API/ABI.

Since some minor bump were not done, some entries present the same
libavutil minor (which represent the next bump after the corresponding
change).

Remove duplicated entry regarding PIX_FMT_BGR48LE/BE formats.

Rename it to AVDictionary, since it will be used as such.  Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

The options -loglevel LEVEL -debug FLAGS can be used for achieving the
same objectives, with a finer level of control.

Use -vismv 1 instead. Simplify.

Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function.

For the moment we don't have sample formats with a non-integer number
of bytes, in that case we may need to create a new
av_get_bits_per_sample() function. In the meanwhile we prefer to adopt
this variant, since avoids divisions by 8 all over the place.

It is a more search-friendly alternative to the ^ operator.

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.

This is consistent with the order of parameters in
av_samples_fill_arrays().

The new layout is consistent with that of the av_image_() API, and
simplifies understanding and copy operations, it also preserves
alignment information which was lost with the previous layout.

This breaks API/ABI, but since the function was never referenced in
the code (and it isn't unlikely already used by someone) then this
should not be a problem.

The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.

Useful for mimicking the ffmpeg -i FILE syntax.

This allows a more efficient use of the commandline.

Allow to free the buffers cached in each AVFilterLink pool.
Fix leak.
