794fcf79a8 Rename CONFIG_FFT_FLOAT ---> FFT_FLOAT 
The define does not originate from configure, so it should not
have a name that is CONFIG_-prefixed.

63debaa74c libopusenc: Change default frame duration to 20 ms 
20 ms is the default in the libopus encoder, and gives better
quality than 10 ms.

adb199d1bc kgv1dec: replace forcing EMU_EDGE by a copy 
The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on
get_buffer2() to always provide buffers with linesize == 2 * width.
This is wrong, since we place no such restriction on get_buffer2()
implementations.

Fix this by decoding into internal buffers and copying them to output
frames. Since this is a very obscure decoder, the performance hit should
not be an issue.

6bfdb2de88 dcadec: set the output channel mode more accurately. 
When downmixing 2.1 to 2-channel, if the 2.0 portion is Lt/Rt, sum-difference or dual mono, the actual output will be the same (with the LFE either mixed-in or discarded).

Also, when downmixing an arbitrary layout to 2-channel, if the bitstream contains custom downmix coefficients targeting Lt/Rt, then the output will be Lt/Rt rather than regular Stereo.
