fluidsynth: performance improvements
* Use floats instead of double for sound calculations. This improves
performance notable and was default for version 1.1.6 using autotools.
* Fix buffer overrun when using floats
* Make use of ARM NEON for multithreading enabled
Performance and sound correctnes was tested with qtractor and a reworked
version of fluidsynth-dssi [1-2]. Tests were performed for single- and
multithreading enabled.
