- Changed the logic significantly to just guarantee there's only ever a
single inactivity timer per connection
- Updated language.expire_subnet btest which is unduly sensitive to
timer-related changes

avoid scheduling redundant inactivity timers
Changed some configuration defaults to potentially more same values.
The callback function is now a hook to allow costomization of the events
that are raised.
Tests now exist. Test baselines are updated.
These are no longer loaded by default due to the performance impact they
cause simply by being loaded (they have event handlers for commonly
generated events) and they aren't generally useful enough to justify it.
