We can't just update the state of the connector and CRTC from KMS since it might contain too new updates, e.g. from a from a future hot plug. In order to not add ad-hoc hot plug detection everywhere, predict the state changes by looking inside the MetaKmsUpdate object, and let the hot-plug state changes happen after the actual hot-plug event. This fixes issues where connectors were discovered as disconnected while doing a mode-set, meaning assumptions about the connectedness of monitors elsewhere were broken until the hot plug event was processed.
