GETCONF doesn't resolve "auto" settings
Right now tor doesn't resolve
auto settings when reporting them via
GETCONF. This means the controller might need to know beforehand how tor will behave for any given
auto setting, which might change across tor versions or even across consensuses. We should have a way to resolve
auto settings so controllers can discover what setting tor will actually use.
Implementing this could be a lot of work because I think the behavior of many
auto values gets determined by code in the relevant subsystem rather than in a centralized place like control.c.
