When a relay starts testing reachability, log its IPv6 ORPort.
The existing code logs the IPv4 ORPort and DirPort.
The IPv4 ORPort is required. The other ports are only logged if they
are present.

Change some function names to distinguish between:
* client first hop reachability (ReachableAddresses)
* relay port reachability self-tests

Split "can extend over IPv6" and "has advertised IPv6 ORPort" into
separate functions. They currently have the same result, but this may
change in 33818 with ExtendAllowIPv6Addresses.
Part of 33817.
Refactor circuit_open_connection_for_extend(), splitting out the IP
address choice code into a new function.
Adds unit tests. No behaviour changes in tor.
Part of 33817.
Allow extend cells with IPv6-only link specifiers.
Warn and fail if both IPv4 and IPv6 are invalid.
Also warn if the IPv4 or IPv6 addresses are unexpectedly internal,
but continue with the valid address.
Part of 33817.
circuit_extend() may be called when a client receives an extend cell,
even if the relay module is disabled.
Log a protocol warning when the relay module is disabled.
Part of 33633.
Return early when there is no suitable IPv6 ORPort.
Show the address and port on error, using a convenience function.
Code simplification and refactoring.
Cleanup after 32588.
When IPv6 ORPorts are set to "auto", tor relays and bridges would
advertise an incorrect port in their descriptor.
This may be a low-severity memory safety issue, because the published
port number may be derived from uninitialised or out-of-bounds memory
reads.
Fixes bug 32588; bugfix on 0.2.3.9-alpha.
