6533514372 Improve soundtouch.clear() so that it really clears TDStretch & RateTransposer states 
Improve soundtouch.clear() so that it really clears all TDStretch &
RateTransposer state variables. Before this clear() left last processed
sample or fractional position state uncleared, which caused slightly
different result if same stream was processed again after clear().

81b0d74727 Correct initial skip value 
... so that with nominal tempo the expected best sequence overlapping
location lays in middle of the correlation window. This will ensure that
with output should be similar to input when tempo adjustment is zero.

5e76cf2f6d Disable skipping of unaligned SIMD memory offset by default 
Change default setting so that SIMD does not skip of unaligned memory
offsets, as that likely is not a necessary compromise with concurrent
CPUs any more.

bf3cec0244 Improvements to help compiler autovectorization 
Refactored FIRfilter and TDStretch hot-spot routines to help compiler
perform more efficient autovectorization.

Benchmarked:
- 2x/3x improvement in gcc-generated x86 SIMD code execution
  times for SSE2/AVX instruction extensions accordingly, when
  hand-tuned SSE intrinsics were disabled. Hand-tuned SSE code
  still is slightly faster than gcc-produced AVX.
- 2.4x improvement for cumulative ARM NEON tunings when compared to
  previous SoundTouch release.

- NEON detection in configure file
- Remove manual loop unrolling, gcc autovectorization does better job
without manually unrolled loops.

fe15975a21 BPMDetect: Make conversion from size_t to int explicit 
Fixes warning C4267 on MSVC.

This assumes that `beats.size()` should never overflow `int` - if that
could happen, the API should likely be changed to handle it gracefully.
