We don't need to log that we're about to look for a channel for a
given extend_info_t, since we're either going to log that we're
launching one (at info), or that we're using an existing one (at
debug).
In practice, there will be at most one ipv4 address and ipv6 address
for now, but this code is designed to not care which address is
which until forced to do so.
This patch does not yet actually create extend_info_t objects with
multiple addresses.
Closes#34069.
The find_my_address() function now prioritize the local interface over the
local hostname when guessing the IP address.
See proposal 312, section 3.2.1, general case:
https://gitweb.torproject.org/torspec.git/tree/proposals/312-relay-auto-ipv6-addr.txt#n359
The entire unit tests had to be refactored to make this possible. Instead of
hot patching it, it has been rewritten to cover all possible cases and the
test interface has been changed to accomodate both IPv4 and IPv6 in order for
them to be tested identically.

Now instead of saying "DONE, DONE" or "MISC, MISC" or "TLS_ERROR,
TLS_ERROR", we can finally give a nice sensible "TLS_ERROR,
wrong version number" which should help debug a great deal.
Closes ticket 32622.
These tests don't actually exercise the authority IPv6 ORPort
self-add feature in 32822, but they do improve coverage of the
related config code.
Part of 32822.
Authorities currently add themselves to the trusted dir servers list,
but if they have an IPv6 ORPort, they leave it out.
This commit makes authorities add their own IPv6 ORPort to the trusted
dir servers list.
Closes ticket 32822.
The exposed interface is "stats/" thus make the unit tests clear that it is
testing that specific GETINFO command.

This is in response to a question about why we don't always log
orport self-tests as reachability tests.
I'm not 100% convinced that bandwidth self-tests are still useful,
but that's an issue for another day. :)
This function is about learning if a given address is local to us as in the
resolved address as a relay.

New name reflects that the function is only used to compare router addresses
in order to learn if they are in the same network.
The network check is /16 and /32 respectively for IPv4 and IPv6.

Only warn when we actually want a commit _and_ there are uncommitted changes
found. Else, it is fine to rename if the script is not creating a commit.

If at least one Address line is given but invalid, we should not attempt to
guess our address.
This commit sends back the "bail" signal so find_my_address() can return an
error if the requested family doesn't exists but still an Address line is
found which is likely another family.

When going over all Address lines from the configuration, continue to attempt
resolving other lines if one fails.
Before that, we would bail right away and never noticed the other Address
lines.

In get_address_from_config(), we would attempt to resolve an Address line that
is not from the requested family but that line could be a valid address from
another family (v4 vs v6).
This makes it that we don't attempt to resolve a valid address from another
family.
Found with unit test config/find_my_address_mixed.

This unit tests validates the use of IPv4 _and_ IPv6 together as in multiple
option Address lines both addresses and hostnames.

This is not actually a bug! It can happen for a bunch of reasons,
which all boil down to "trying to add an extrainfo for which we no
longer have the corresponding routerinfo".
Fixes#16016; bugfix on 0.2.6.3-alpha.
