service_intro_point_new() and hs_desc_link_specifier_new() need to take a node_t, so they can fill it in with IPv4 and IPv6 addresses.

These tickets aren't urgent, and they involve major refactoring.
Deferring to 0.3.3

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.

These tickets, tagged with 034-removed-*, are no longer in-scope for 0.3.4. We can reconsider any of them, if time permits.

We can implement this ticket easily by replacing the link specifier part of service_intro_point_new() with get_lspecs_from_node().

This refactor completes part of #23759.

See my branch bug23576 on

This refactor also puts intro IPv6 link specifiers in onion service descriptors (#26992).

It passes make check and make test-network-all on my machine, but will probably fail Appveyor CI due to #26986.

This looks good and I like the code simplification!

I left a few nitpicks on the PR that you might want to handle.

Also, should we try to rebase this so that we can see the appveyor green checkmark (now that #26986 got fixed)?
