This patch adds definitions of the new Advertisement Monitor Device
Found and Device Lost events to indicate that the controller has
started/stopped tracking a particular device.

Reviewed-by: Miao-chen Chou <mcchou@google.com>
---

Changes in v5:
- Update the Adv Monitor Device Found event to include fields from the
  existing Device Found event.

Changes in v4:
- Add Advertisement Monitor Device Found event.

Changes in v3:
- Discard changes to the Device Found event and notify bluetoothd only
  when the controller stops monitoring the device via new Device Lost
  event.

Changes in v2:
- Instead of creating a new 'Device Tracking' event, add a flag 'Device
  Tracked' in the existing 'Device Found' event and add a new 'Device
  Lost' event to indicate that the controller has stopped tracking that
  device.
