6ed3b504f9 Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables.
This symbol is only ever used to calculate the non-hardcoded tables, so
only enable it in that case, and static to the source unit that uses it.

dc7e07ac1f Add stereo rematrixing support to the AC-3 encoders.
This improves the audio quality significantly for stereo source with both the
fixed-point and floating-point AC-3 encoders.
Update acodec-ac3_fixed and seek-ac3_rm test references.

63e8d9760f Use the new libavcore audio channel API.
This also allows to remove a linking dependency of libavfilter on
libavcodec.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

306a1204ff Update AC-3 channel map. 2F/2R layout only has 4 channels. This correction
does not change any current channel mapping behavior.

bad5537e2c Use full internal pathname in doxygen @file directives.
Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
