Comment (by teor):
In my commit b4aa8fc3d9 in my branch bug23820_032 (#23820), I ripped out
IPv6 support in these functions. We'll need to revert that commit, and
then fix the issues in the function.
{{{
Remove buggy IPv6 support from pick_intro_point() and
service_intro_point_new()
The previous version of these functions had the following issues:
* they can't supply both the IPv4 and IPv6 addresses in link
specifiers,
* they try to fall back to a 3-hop path when the address for a direct
connection is unreachable, but this isn't supported by
launch_rendezvous_point_circuit(), so it fails.
But we can't fix these things in a bugfix release.
Instead, always put IPv4 addresses in link specifiers.
And if a v3 single onion service can't reach any intro points, fail.
