cd15b7c03d samplefmt: make av_samples_alloc() initialize the data to silence.
Right now the buffer is zeroed, which does not represent silence for U8(P).

83b26046fc avutil: change default buffer size alignment for sample buffer functions
Aligning nb_samples will give both correct plane pointer alignment and enough
padding for SIMD-optimized functions.

a6703faa15 samplefmt: add av_get_bytes_per_sample()
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.

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.
