for peeking at a FIFO buffer data.

d9f80ea2a7 Move metadata API from lavf to lavu. 
Rename it to AVDictionary, since it will be used as such.  Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

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.

bebe72f4a0 lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enums 
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.

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.

4cabef0a9d Make strmatch() return 1 only if the string compared against the 
prefix does not contain other characters which may belong to an
identifier.

This allows to distinguish for example to have different constants
with the same prefix (e.g. "foo" and "foobar").
