afd482f51b midi: Recalculate (and rename) the note frequency table. 
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.

abb7d1dcfe plugin_midi: expand gustable[] to 128 entries 
The code assumes that gustable[] has 128 entries, while it
only had 120. Since the entries follow a simple pattern (they
seem to be note frequencies, so each entry is the previous one
multiplied by the 2^(1/12)), expanding the table is the simple
fix.

2afc175a4e 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.

23d9812273 loader-initialized global plugin API: 
struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api

the loader uses this pointer to initialize rb before calling entry_point

entry_point is no longer passed a pointer to the plugin API

all plugins, and pluginlib functions, are modified to refer to the
global rb

pluginlib functions which only served to copy the API pointer are
removed

b2f1b5dd18 ---------------------------------------------------------------------- 
Added Karl Kurbjun's sound output patch, cleaned up some output.
Main file is now midiplay.c, midi2wav is still in there for anyone who
wants it. Set sampling rate to 22k, and increased note decay time.
Reduced number of concurrent active voices and made new notes replace
used voices if none are available. This makes lag less apparent.
I really hope this wont go red. (turns around and runs)
