bd6ab90ad4 core/or: Support IPv6 EXTEND2 cells 
Allow clients and relays to send dual-stack and IPv6-only EXTEND2 cells.
Parse dual-stack and IPv6-only EXTEND2 cells on relays.

Relays do not make connections or extend circuits via IPv6: that's the
next step.

Closes ticket 33901.

8c55d34e0a core/or: Accurately log remote relay IPv6 addresses 
Log IPv6 addresses on connections where this relay is the responder.

Previously, responding relays would replace the remote IPv6 address with
the IPv4 address from the consensus.

(The port is replaced with the IPv6 ORPort from the consensus, we will
resolve this issue in 33898.)

41fa07f751 core/or: Allow IPv6 connections to be canonical 
Consider IPv6 addresses when checking if a connection is canonical.

In 17604, relays assumed that a remote relay could consider an IPv6
connection canonical, but did not set the canonical flag on their side
of the connection.

78bcfc1280 circpad_setup_machine_on_circ(): exit early on error. 
This function does a nonfatal assertion to make sure that a machine
is not registered twice, but Tobias Pulls found a case where it
happens.  Instead, make the function exit early so that it doesn't
cause a remotely triggered memory leak.

TROVE-2020-004.

894ff2dc84 dos: Pass transport name on new client connection 
For a bridge configured with a pluggable transport, the transport name is
used, with the IP address, for the GeoIP client cache entry.

However, the DoS subsystem was not aware of it and always passing NULL when
doing a lookup into the GeoIP cache.

This resulted in bridges with a PT are never able to apply DoS defenses for
newly created connections.

Fixes #33491
