controlport unix sockets

We may want to keep an eye on controlports moving to unix sockets:

In the glorious future, maybe Tor packages will default to using
an abstract unix ControlSocket:
Support abstract namespace AF_UNIX sockets. (#20337) · Issues · Legacy / Trac · GitLab
and then they wouldn’t be tempted to using ControlPorts at all.


Whonix 14 will be using control socket only. [already done]
