The probe task.
Send a SOA UDP query to see if the zone needs to be updated (or similar, potential, HTTP probe query) and check serial number. If yes, start the auth_transfer task. If no, make sure auth_nextprobe timeout wait task is running. Needs to be a task, because the UDP query needs an event entry. This task could also be started by eg. a NOTIFY being received, even though another worker is performing the nextprobe task (and that worker keeps waiting uninterrupted).
| struct auth_master* auth_probe::scan_specific |
once notified, or the timeout has been reached.
a scan starts. the scan specific target (notify source), or NULL if none
