These tickets, tagged with 034-removed-*, are no longer in-scope for 0.3.4. We can reconsider any of them, if time permits.

I don't think we should fix these bugs in the Tor C code.

Instead, we should move these counters to the PrivCount Rust code (and add v3 onion service statistics at the same time).
