OpenWRT dynamic IP watchdog

[Aleksandr V. Piskunov]

Yes, I've tried 135 first, but during the real usage there were quite
a few false alarm situations with watchdog reconnecting at
136..~140 seconds. So.. changed it to 150 secs, which seems to work OK
for my conditions.

I can try to send a git patch to contrib/examples/reresolve-dns,
if rest is OK.

Regards,
Aleksandr
