midi: Recalculate (and rename) the note frequency table.

2017-01-06T18:29:00+00:00

gustable[] contained plain note frequencies in milliHertz, but
was named and documented to appear like a table of magic numbers.
The values also seemed to be slightly inaccurate (up to about
0.01Hz, so probably irrelevant).

This changes the name to freqtable to make the purpose clearer, and
uses slightly better values.

midi: make the patch sample data pointer a *int16_t to get rid of some ugly casting and drop an acessor macro to make caching the pointer in the synthVoice loop possible. Speeds up midi by 1-2% on cf and 3-5% on PP.

Do not duplicate const table, make getEvent function static inline, gives about a ~1.5% speedup, put tick function in iram, ~3.5% speedup
