fixes Bug 225

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.

That way all mix levels as exported by the parser
will have the same meaning.

Previously the 3bit center mix level for eac3 was
used to index in a 4 entry table leading to out of array reads.
this change removes the table and offsets the ac3 variable by 4
so it matches the meanings for eac3 except the reserved case.
The reserved case is then explicitly handled.

It's used in lavf.

and decoder, and vice-versa for the AC-3 encoder.

Done to keep ABI compatible. Otherwise this is just silly

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.

None of these symbols should be accessed directly, so declare them as
hidden.

Other parts of FFmpeg use NE (native endian) rather than ME (machine).
This makes it consistent.

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).
Fixes Issue 2022.
