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.

a0fc780a20 arm64: int32_to_float_fmul neon asm

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().

synth_filter_float_c:    1866.2       3490.9
synth_filter_float_neon:  915.0       1531.5

With fftc.imdct_half forced to imdct_half_neon:

71617884a2 aarch64: h264 chroma motion compensation NEON optimizations
Since RV40 and VC-1 use almost the same algorithm so optimizations for
those two decoders are easy to do and included.
