8487cd0204 Start using C89-style for loop initial declarations for 
reusable code module parts that we reuse in other projects. It's
a huge maintenance burden having to change this stuff around everytime
when compiling in non-C99 mode

between phases.

bebe0d78a7 Optimize sinc for AVX as well. 
Disable it for now however, as it's slightly slower
than SSE1 for the few taps we're using.

From testing, it's 10-20% faster when number of taps are increased.
The AVX path might need some more tuning, but it's fair to
assume the algorithm is memory bound.

b8abf34785 Purge some now useless code. 
Removes manual input rate adjustments.
Don't allow DSP plugs to resample as it would complicate things alot
with dynamic rate control.
Also purges optional ssnes_* symbols for external plugs.
