Reimar Döffinger 4c886d613d Detect byte-swapped AC-3 and support decoding it directly. 
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.
