Diego Biurrun 01621202aa build: miscellaneous cosmetics 
Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.

foo86 ae5b2c5250 avcodec/dca: add new decoder based on libdcadec 2016-01-31 17:09:38 +01:00
foo86 4608996772 avcodec/dca: remove old decoder 
Remove all files and functions which are not going to be reused,
and disable all functions and FATE tests temporarily which will be.

Janne Grunau 705f5e5e15 arm64: port synth_filter_float_neon from arm 
~25% faster dts decoding overall. The checkasm CPU cycles numbers are
not that useful since synth_filter_float() calls FFTContext.imdct_half().
