Modifies WaitEvent and WaitEventTimeout to actually wait instead of polling When possible use native os functions to make a blocking call waiting for an incoming event. Previous behavior was to continuously poll the event queue with a small delay between each poll. The blocking call uses a new optional video driver event, WaitEventTimeout, if available. It is called only if an window already shown is available. If present the window is designated using the variable wakeup_window to receive a wakeup event if needed. The WaitEventTimeout function accept a timeout parameter. If positive the call will wait for an event or return if the timeout expired without any event. If the timeout is zero it will implement a polling behavior. If the timeout is negative the function will block indefinetely waiting for an event. To let the main thread sees events sent form a different thread a "wake-up" signal is sent to the main thread if the main thread is in a blocking state. The wake-up event is sent to the designated wakeup_window if present. The wake-up event is sent only if the PushEvent call is coming from a different thread. Before sending the wake-up event the ID of the thread making the blocking call is saved using the variable blocking_thread_id and it is compared to the current thread's id to decide if the wake-up event should be sent. Two new optional video device methods are introduced: WaitEventTimeout SendWakeupEvent in addition the mutex wakeup_lock which is defined and initialized but only for the drivers supporting the methods above. If the methods are not present the system behaves as previously performing a periodic polling of the events queue. The blocking call is disabled if a joystick or sensor is detected and falls back to previous behavior.
