#33633)
I am most of the way through this change:
* tor considers IPv6-only extend requests valid
* tor checks IPv4 and IPv6 addresses before extending
* tor re-uses existing IPv4 and IPv6 connections for extends
I still need to initiate new IPv6 connections in response to extend
requests.
Here is the draft PR, with #33899, #33901, and #33917:
* don't merge: https://github.com/torproject/tor/pull/1864
The PR also has #33918, but the next push will drop that commit - we can
review and merge it separately.
