The Clock framework allows users to specify a callback which is called after the clock's period has been updated. Some users need to also have a callback which is called before the clock period is updated. As the first step in adding support for notifying Clock users on pre-update events, add an argument to the ClockCallback to specify what event is being notified, and add an argument to the various functions for registering a callback to specify which events are of interest to that callback. Note that the documentation update renders correct the previously incorrect claim in 'Adding a new clock' that callbacks "will be explained in a following section".
