e6d9fa66f1 ac3dec: Move center and surround mix level tables to the parser. 
That way all mix levels as exported by avpriv_ac3_parse_header()
will have the same meaning.

Previously the 3-bit center mix level for E-AC-3 was used to index in a
4-entry table, leading to out-of-array reads.

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.

a26f1d1092 ac3: make the value of codec_id during (E-)AC-3 parsing stay CODEC_ID_EAC3 
if any E-AC-3 frames have been detected instead of switching back and forth for
AC-3 core + dependent E-AC-3 substream(s).
