o Minor features (control port, relay):
- Introduce "GETINFO address/v4" and "GETINFO address/v6" in the control
port to fetch the Tor host's respective IPv4 or IPv6 address. We keep
"GETINFO address" for backwords-compatibility which retains the current
behavior. Closes ticket 40039. Patch by Neel Chauhan.
