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

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

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

cd963d84ca MIDI: Allow seeking forward and backward using the left/right keys. Currently seeks in 5 second
increments, but this can be set to any amount. Also implemented a counter for playing time, which can 
pretty easily be used to determine the length of the file, in seconds, before playing it. The time 
isn't displayed anywhere right now, but all this can be useful if this thing is turned into a codec, or 
at least gets a nice UI.

c3584c0d63 MIDI: Scale each instrument by a calibration value, since not all patches are at the same base volume.
This should make some files sound more natural, without some instruments overpowering others. 
Ultimately, these values need to be moved to the config file, and the table should probably be put in 
IRAM or something.

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

1ba018bb01 Add drum names, make cowbell a default instrument (no way to remap them from UI yet). Add non-static
wrapper for pressnote (is there a better way?). Beatbox only tested on H300; compile at own risk.

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)
