Comment (by teor):

 It turns out that the majority of this ticket can be implemented by
 checking ClientUseIPv4 and ClientUseIPv6 when checking the fascist
 firewall settings for OR and Dir connections. This is implemented in
 #17840.

 We don't even need to switch between IPv4 and IPv6 on dual-stack hosts.
 The random node selection already does that for us - in proportion to the
 IPv4/IPv6 consensus weight ratio.
 (Which is a desirable property.)

 This ticket might be able to be closed after testing #17840 to see if it
 makes connections on the wrong address family.
