[FFmpeg-devel] [PATCH v2 00/16] Replace native DCA decoder with libdcadec based one

[foo86]

Updated version of the patch. I choose to split it into even smaller commits to
make reviewing easier; you may prefer to squash it as needed.

Changes since the first version:

* Removed checkasm test for dcadsp
* Removed FATE test for dca-xll (didn't check if this works)
* Core decoder now uses butterflies_fixed() for sumdiff decoding
* avpriv_request_sample() is now used for reporting missing features
* Core decoder now stays in fixed point mode during intermittent XLL decoding errors
* X96 extension is no longer parsed (and left unused) when decoding XLL
* Minor code refactoring
