Comment(by ln5):

 (Meh, lost all changes in that last update. :-( Trying to recreate.)

 The need for config option(s) increase when clients start connecting to
 public relays (#4564).

 We should take into account protection of clients without "privacy
 enhancements for SLAAC" enabled (i.e. carrying their MAC address in
 their IPv6 address) (#4806).

 I see these needs for clients:

 - Prefer IPv6 over IPv4 OR ports (default: 0)

   Default 0 saves clients with an IPv6 address but no IPv6
   connectivity to the relay from get stuck. (And also saves against a
   disaster with a buggy IPv6 implementation.) It also saves clients
   from potentially leaking their MAC address.

 - Fall back to another address family for the same relay if the
   current one fails (default: 0)

   Default 0 saves clients from leaking their MAC.

   We might want clients running with bridges to default to 1 -- the
   user entered an IPv6 address manually after all.

 - Use only IPv6 (default: auto)

   'auto' translates to 1 on a system without IPv4 support, otherwise 0.

   Or we could have "Clients use IPv4 (default: auto)" and "Clients use
   IPv6 (default: auto)".


 There might be other needs for relays. They differ enough from client
 needs to have their own config options.
