Add three new classes, EventDispatcher, EventNotifier and Timer, that define APIs for file descriptor event notification and timers. The implementation of the EventDispatcher is meant to be provided to libcamera by the application. The event dispatcher is integrated twith the camera manager to implement automatic registration of timers and events.
