tracing: Add hist trigger action hook
Add a hook for executing extra actions whenever a histogram entry is added or updated. The default 'action' when a hist entry is added to a histogram is to update the set of values associated with it. Some applications may want to perform additional actions at that point, such as generate another event, or compare and save a maximum. Add a simple framework for doing that; specific actions will be implemented on top of it in later patches.
