Sometimes, for example when we ask the uCode for calibration, we wait for the "complete" response while we also need the results that are sent in other, interim, notifications. Currently we handle this by installing an RX handler globally, but that isn't needed as this is the only time we want to use these notifications. So in order to be able to simplify at least future code that does the same, extend the notification wait framework to allow you to wait for multiple commands and decide based on the command whether the wait finished. While at it, also fix a race that can then become relevant -- if the wait function has returned true once it shouldn't be called again, today this can happen due to races between the triggering and the wakeup.
