Updating Google Domains from DD-WRT

I have had a Netgear WNDR3700v2 router for a few years already and I bought this model specifically because I could flash it with the open-source DD-WRT firmware.

Yes, this machine is very slow, but that's the whole point of the exercise I'm going to narrate below. I recently got approval from the NetBSD core team to import Kyua into the NetBSD source tree and replace ATF with it.
