/*input stubs
in_generic.c should make these kinda useless, but sometimes you need more than the following three functions:
void IN_JoystickAxisEvent(unsigned int devid, int axis, float value);
void IN_KeyEvent(unsigned int devid, int down, int keycode, int unicode);
void IN_MouseMove(unsigned int devid, int abs, float x, float y, float z, float size);
that said, if they're enough, then just call those in Sys_SendKeyEvents. You can also call them from other threads just fine.
their devid values should be assigned only when a button is first pressed, or something, so controllers get assigned to seats in the order that they're pressed. so player 1 always hits a button first to ensure that they are player 1.
or just hardcode those based upon usbport numbers, but that's unreliable with usb hubs.
