os_sysinit: any platform-dependent setup that needs to occur directly upon startup.
This code is processed right as soon as main() starts.

os_sdlinit: any platform-dependent setup that needs to occur after SDL is up and running.
Currently only used on the Wii in order to get the Wiimote working.

os_sdlevent: preprocessing for SDL events.
This is used to hack in system-dependent input methods (e.g. F16 and other scancodes on OS X; Wiimote buttons;
etc.) If defined, this function will be called after capturing an SDL event.
A return value of 0 indicates that the event should NOT be processed by the main event handler.
