More things I wanted to say:

- Support for the old ENVSYS_GTREDATA and ENVSYS_GTREINFO ioctls
  is implemented, so old envstat(8) and other apps using the old
  framework work perfectly.
- If there are no items on the sysmon envsys events linked list, the
  workqueue(9) is destroyed and the callout(9) stopped.
- Old powerd(8) won't work anymore because POWER_EVENT_MSG_SIZE
  is now 128 bytes, where previously it used 32 bytes. There's no easy
  way to support the old powerd.
