Interface implemented by keyboard controllers. Used by consoles to send keyboard events to the controller.
The function keyboard_event() takes the keyboard controller as its first argument obj. The key_up argument specifies whether the event is a key release (1) or a key press (0). The key argument is the Simics internal keycode, as defined in src/extension/common/keycodes.h.
If the return value is 1 the keyboard controller accepted the event. If return value is 0 the keyboard controller did not accept the event, and the console should buffer the event until it gets a keyboard_ready() call from the keyboard controller.
