Everytime we try to discover an address we want to publish, emit a log notice
if we are unable to find it even though an ORPort was configured for it.
Because the function can be called quite often, we rate limit that notice to
every hour so it gets annoying just enough so the operator fixes that.

We would before do an address discovery and then a lookup in the cache if not
found which is now simplified by calling relay_find_addr_to_publish() directly
which does all those combined.
Furthermore, by doing so, we won't trigger an address discovery every minute
if we have no ORPort configured for the family.

Now that relay_find_addr_to_publish() checks if we actually have an ORPort, we
can simplify the descriptor building phase for IPv6.
This also avoid triggering an IPv6 discovery if the IPv4 can't be found in the
first place.

In other words, if we don't have an ORPort configured for a specific family
(IPv4/v6), we don't bother doing address discovery.

This is a _subtle_ bug introduced by d1494d14, which resolved
connections that was allocated in the extorport/handshake test. So
how did the connection get freed? Our test was set up so that every
extorport connection would get the same ext_or_id. Two connections
couldn't have the same ext_or_id, and if they did, one would get
freed. This meant that the _next_ connection to be constructed in
the test would cause the previous connection to become closeable,
even if it hadn't been closeable before.
But when we applied d149d14, we stopped making it so our code
enforced this uniqueness, and thereby make it so we _weren't_
freeing this connection in the tests.
Closes#40260; bug not in any released version of Tor.
Let external bridge reachability testing tools discard cached
bridge descriptors when setting new bridges, so they can be sure
to get a clean reachability test.
Implements ticket 40209.
Generates the compile_commands.json file using the "bear" application so the
ccls server can be more efficient with our code base.

This step happens after we make each consensus flavor, and before we
worry about sigs or anything. That way if Tor crashes, or if we fail to
get enough sigs, we still have a chance to know what consensus we wanted
to make.
This validation was only done if DisableNetwork was off because we would use
the global list of transports/bridges and DisableNetwork would not populate
it.
This was a problem for any user using DisableNetwork which includes Tor
Browser and thus leading to the Bug() warning.
Without a more in depth refactoring, we can't do this validation without the
global list.
The previous commit makes it that any connection to a bridge without a
transport won't happen thus we keep the security feature of not connecting to
a bridge without its corresponding transport.

Don't pick the bridge as the guard or launch descriptor fetch if no transport
is found.
