Comment:

 Please see my branch bug23820_032. It removes buggy IPv6 support from v3
 single onion services, and adds an option check and some logging.

 Somewhat alarmingly, I didn't break any unit tests with these changes.
 But if we want unit tests here, someone else will need to write them,
 because I've run out of time to do this.
