midi plugin: make local functions static where possible

Change-Id: I702755529f98015586b5b9592ced75cf7591880c

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.

loader-initialized global plugin API:

2009-01-16T10:34:40+00:00

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

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

Macros should be ALL CAPS, so rename (un)likely() to (UN)LIKELY()

Turns out that using likely in the loop condition gives a nice little speedup to so let's do it.

Introduce likely() and unlikely() macros, use to give gcc hints about which branch is likely to be taken in a conditional, use them in the midi player for a small speedup, use instead of similar EXPECT macros in tremor and use in mpegplayer
