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.

This is needed by the new AVOptions API.

Since we now always allocate it, it can simply be made part of the context
instead.

Deprecate corresponding AVCodecContext option.

This is the first test of decoder private options.

av_get_bits_per_sample_fmt() is deprecated.

This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.

Depending on error_recognition is not correct, low values do
certainly not mean it is ok to crash.
