IP address (in a single API call). Tor should support both styles of
networking API.
+ In particular, if binding to all IPv6 addresses fails, relays should still
+ try to discover their public IPv6 address, and check the reachability of
+ that address. Some OSes may not support the IPV6_V6ONLY flag, but they may
+ instead bind to all addresses at runtime. (The tor install may also have
+ compile-time / runtime flag mismatches.)
+
If both reachability checks succeed, relays should publish their IPv4 and
IPv6 ORPorts in their descriptor.
