It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.

It allows to search for options only with AVClass, without allocating
the corresponding context.

The new function provides a more generic interface than av_fifo_peek()
for peeking at a FIFO buffer data.

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

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.

Also deprecate avcodec_get_pix_fmt_name() in its favor.

Also deprecate av_get_pict_type_char() in favor of
av_get_picture_type_char().

The new enum and av_get_picture_type_char() are defined in libavutil.
This allows the use in libavfilter without the need to link against
libavcodec.

They've accumulated enough new APIs and corresponding deprecated cruft.

This breaks API and ABI.

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.

The bumps are for adding version.h and avio_{get/put}_str functions in
lavf and making av_dlog public in lavu.
