 In #32637, we made clients default to "PreferIPv6" on SOCKSPorts (and
 other client ports).

 But in #33796, we discovered that this change broke torsocks.

 We want to defer this change to 0.4.4, so tor can implement IPv4-only and
 IPv6-only resolves for torsocks.

 Since #32637, we have also merged:
 * #33608, which removes a forced PreferIPv6 for non-SOCKSPorts
 * #32994, which puts the PreferIPv6 default in port_parse_config(), rather
 than in 2 different places in the code

 So it should be very easy to change the default for PreferIPv6.
