This function tried to modify an array in place, but did it in a
pretty confusing and complicated way. I've revised it to follow a
much more straightforward approach.
Fixes bug #40065.
On an IPv6 reachability failure test, if the address was configured, don't
publish the descriptor and log warn. If the address was auto discovered, still
publish the descriptor.
Closes#33247.

Enum allows us to easily compare what is being returned but also better
semantic to the code.

Now support IPv4 _and_ IPv6.
This also cleans up nicely the function that was moving IPv4 addresses from
uint32_t to tor_addr_t.

Without this fix, if an PT forgets to send a USERADDR command, that
results in a connection getting treated as local for the purposes of
rate-limiting.
If the PT _does_ use USERADDR, we still believe it.
Closes ticket 33747.
In routerconf_find_ipv6_or_ap(), we check if the returned ORPort is internal
but not for listening. This means that IPv6 [::] is considered internal.
Thus, we can't use it, we have to look directly at the configured address and
port and if they are valid, we do consider that we have a valid IPv6 ORPort
and that we can thus extend in IPv6.

Now that tor automatically binds to IPv4 _and_ IPv6, in order to avoid
breaking configurations, we sanitize the parsed lists for duplicate ORPorts.
It is possible to happen because we still allow this configuration;
ORPort 9888
ORPort [4242::1]:9888
Meaning that the first ORPort value will bind to 0.0.0.0:9888 _and_ [::]:9888
which would lead to an error when attempting to bind on [4242::1]:9888.
However, that configuration is accepted today and thus we must not break it.
To remedy, we now sanitize the parsed list and prioritize an ORPort that has
an explicit address over the global one.
A warning is emitted if such configuration pattern is found. This is only for
the ORPort.

This commit makes it that if the ORPort is set with a single port, it will
bind to both global listen IPv4 and IPv6 addresses.
To pin an "ORPort <PORT>" to be IPv4 or IPv6, the IPv4Only/IPv6Only flags are
honored thus this will _only_ bind on IPv6 for that port value:
ORPort 9050 IPv6Only
Results in: [::]:9050
ORPort 9051 IPv4Only
Results in: [0.0.0.0]:9051
Attempting to configure an explicit IPv4 address with IPv6Only flag is an
error and vice versa.

These now (or_port and dir_port) now have "find" names, since they
look at the portcfg first, then at the actual ports from the
listeners.

router_has_advertised_ipv6_orport routerconf_has_ipv6_orport \
router_get_advertised_dir_port routerconf_find_dir_port
Rationale: these don't actually give the first advertised
address/port, but instead give us the first such port that we are
_configured_ to advertise. Putting them in a portconf_ namespace
therefore makes sense.
Similarly, there are no other functions that get the first
configured advertised addr/port, so the "by_type_af()" part is needless.

This option controls if a tor relay will attempt address auto discovery and
thus ultimately publish an IPv6 ORPort in the descriptor.
Behavior is from proposal 312 section 3.2.6.

The ORPort can be IPv4Only which means that even if we can auto discover an
IPv6 address, we should not publish it because it would have an ORPort of 0.

Instead of a boolean saying "cache_only" add the concept of flags so we add
semantic through out the code and allow ourselves to have more options in the
future.

Tell the relay find address interface to only use the cache so we don't

At the moment, this command only returns the IPv4. Do so by using the new
relay_find_addr_to_publish().
New commands to return IPv4 and IPv6 will be done with the work in tor#40039.

Use the new relay_has_address_set() interface when deciding if we need to
fetch directory information from an authority as a relay.
If no IPv4 address is found, we'll proceed with a fetch so we can learn our
address in the HTTP header or NETINFO cell that a trusted authority will send
us back.

Tor periodic events have moved to a role base model where relays have specific
events. One of those is to rebuild the descriptor and that is ran every
minute.
This removes the call to router_rebuild_descriptor() from
router_get_my_routerinfo_with_err() because that is the only code path that
can call for a rebuild every second.
Instead, when we mark the descriptor as dirty, immediately reschedule the
descriptor check periodic event so it can be rebuilt that way instead of
randomly when router_get_my_routerinfo_with_err() is called.
