This avoids spurious library rebuilds when only the test program
code is changed and simplifies the build system.

Also replace the last two usages of avpriv_float_dsp_init with
avpriv_float_dsp_alloc.

Arch-specific optimizations are handled this way everywhere else.

It is not supported by all compilers on FATE. Fixes "some test were
skipped" errors.

This fixes fate-float_dsp-test on RVCT 4.0.

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.

This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3)
independent of dsputil.

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.

This makes the aac decoder and all voice codecs independent of dsputil.

Move vector_fmul() from DSPContext to AVFloatDSPContext.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

Thus use templating to compile two different binaries.
