Comment (by teor):
In my commit 20b0e9e07d in my branch bug23820_032 (#23820), I ripped out
IPv6 support in hs_get_extend_info_from_lspecs(). We'll need to revert
that commit, and then fix the issues in the function.
{{{
Remove buggy IPv6 support from hs_get_extend_info_from_lspecs()
The previous version of this function has the following issues:
* it doesn't choose between IPv4 and IPv6 addresses correctly, and
* it doesn't fall back to a 3-hop path when the address for a direct
connection is unreachable.
But we can't fix these things in a bugfix release.
Instead, treat IPv6 addresses like any other unrecognised link specifier
and ignore them. If there is no IPv4 address, return NULL.
}}}
