e05a3ac713 ac3enc: select bandwidth based on bit rate, sample rate, and number of 
full-bandwidth channels.

This reduces high-frequency artifacts and improves the quality of the lower
frequency audio at low bit rates.

79997def65 ac3enc: use generic fixed-point mdct 
This makes the AC3 encoder use the shared fixed-point MDCT rather
than its own implementation.  The checksum changes are due to
different rounding in the MDCT.

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.
