No behavioural change

This makes the use of the node explicit in the function, rather

0cf90bac2a Choose the correct address for one-hop connections
After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.

This likely affected bridge clients with IPv6 bridges.

0ca3f495c6 Fix dnsserv.c assertion when no supported questions are requested.
The problem is that "q" is always set on the first iteration even
if the question is not a supported question. This set of "q" is
not necessary, and will be handled after exiting the loop if there
if a supported q->type was found.

ba6509e9e1 Fix broken directory request to the DirPort
Commit e72cbf7a4 introduced a change to directory_initiate_command_rend()
that made tor use the ORPort when making a directory request to the DirPort.
The primary consequence was that a relay couldn't selftest its DirPort thus
failing to work and join the network properly.

The main issue was we were always considering an anonymized connection to be
an OR connection which is not true.

Fixes #18623

fa07c60c67 Fix another case of 17668: Add NoEdConsensus
I had a half-built mechanism to track, during the voting process,
whether the Ed25519 value (or lack thereof) reflected a true
consensus among the authorities.  But we never actually inserted this
field in the consensus.

The key idea here is that we first attempt to match up votes by pairs
of <Ed,RSA>, where <Ed> can be NULL if we're told that there is no
Ed key.  If this succeeds, then we can treat all those votes as 'a
consensus for Ed'.  And we can include all other votes with a
matching RSA key and no statement about Ed keys as being "also about
the same relay."

After that, we look for RSA keys we haven't actually found an entry
for yet, and see if there are enough votes for them, NOT considering
Ed keys.  If there are, we match them as before, but we treat them
as "not a consensus about ed".

When we include an entry in a consensus, if it does not reflect a
consensus about ed keys, then we include a new NoEdConsensus flag on
it.

This is all only for consensus method 22 or later.

Also see corresponding dir-spec patch.

When generating a vote, and we have two routerinfos with the same ed

This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us.  It is part of bug 18318, and the root cause of 17668.
