Rename the static function update_resolved_cache() to resolved_addr_set_last()
and make it public.
We are about to use it in order to record any suggested address from a NETINFO
cell.

In the spirit of reducing technical debt. Move code that marks a channel as a
client into its own function and document it properly.
No behavior change, only code movement.

In order to process a NETINFO cell, the OR connection needs to go through a
series of validation else we don't process the cell.
Move those into its own function in and improve documentation.
This is an attempt at reducing technical debt of the rather large and
complicated channel_tls_process_netinfo_cell() function.

If at least one service is configured as a version 2, a log warning is emitted
once and only once.

We introduce TOR_EXTRA_PRE_COMMIT_CHECKS environment variable to run the
pre-commit hook. The pre-push git hook will set it in order to run all
pre-commit checks.

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.
