aarch64: float_dsp NEON assembler
...
Ported from arm NEON and added vector_dmul_scalar.
Functions between 1.5 and 5 times faster than the C implementations
using Apple's clang-503.0.19 on A7.

float_dsp: Include config.h for redefining restrict
...
This makes sure that the restrict keyword is mapped to whatever
keyword the compiler prefers/supports. This fixes building on MSVC
(and possibly on GCC 2.x as well).

floatdsp: move butterflies_float from dsputil to avfloatdsp.
...
This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3)
independent of dsputil.

floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.
...
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.
