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.

50a6ca39ad Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 
This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

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

1515ff8522 MIDI: At long last, though quick and dirty, pitch bend depth! Or, I think it works. Tested on two 
files. Let me know if anyone discovers any problems with this. This commit also includes Nils's synth 
loop optimization patch. I hope committing it does not cause problems.

e1940b87b0 Optimisation of the midi player, reducing the number of multiplications and memory accesses inside a very frequently executed loop, also does shifting of the whole sample when synthing is done which improves accurracy slightly, ~10% fewer buffer misses

26d242ae65 General housekeeping: Make plugin buffer functions take size_t * instead of int * to match the parameter type of the buffer functions called in the core. Get rid of unsafe int * <==> size_t * casting. Use ssize_t where int was used and size_t where unsigned int was used in the buffer calls to not alter signedness in the plugins. No API version change since it should only be an issue for 64-bit sim builds.

c84461fb8f More adsr related nonsense, argh! Fix adsr related problem on some notes being stopped instead of 
looped. Ramping code still not quite right, but dont want to lose this.

viewers.

28b5afd05a Optimize synth code by pre-computing the volume scaling for each note. 
Scaling is now calculated once per MIDI event at the most, instead of
once per sample. Increase voice ramping speed, increase number of
active voices a little.

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)
