91a45d2ecc Rename printf to prevent naming conflict. Also change comment to conform with Rockbox standards.

35e8b1429a Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). 
The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.

Should be no functional change to targets or the simulator.

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.

1adc869d9c midi: yield more, fixes flickering backlight fade on some targets while playing midi. Some coding style clean up, it's a little better but still a mess

4c43f7be0a Rearrange the main synth loop a little and move some tests around for a ~5% speedup on c200, increase the output buffer size to make skips less likely, playback of simple midi files should now be mostly skip free on pp based players

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

7f1fbe4af2 MIDI: Increase percision of synthesizer by a factor of 4 - makes certain parts (guitar bends, mostly) 
sound more natural. Also, completely rearrange the order of operations in the delta computation. Had to 
use long longs. Probably not a good idea for speed, but the order can be optimized more later.

0fd4c2e455 Rearrange logic in the synthVoice loop to do less tests and remove need of a struct member for a small speedup, move some memory lookups out of the loop for a small speedup, further cosmetic changes to the synthVoice function. Change isUsed to a bool for clearer logic and also a tiny speedup

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.

ca46a3d095 Increase output buffer size to 32kB, results in less buffer missing in general and avoids buffer misses when lcd remote is plugged in while playing and ticking reduction is enabled. Increase max voices used on coldfire targets to 24 and reduce voices used on pp targets to 16. Put one more struct in iram for a slight speedup on coldfire. Fix comments in midiutil.h

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

414724e2f4 MIDI: Kick up number of voices and decrease the decay rate, taking 
advantage of the recent speedups. Some instruments sound a lot more 
natural now.
