Commonized networking (#3310)

* Fix not being able to connect to local friends socket

* Start basic work on tunneling protocol and move some code into a common crate

* Commonize message serialization logic

* Serialize Base62Ids as u64 when human-readability is not required

* Move ActiveSockets tuple into struct

* Make CI run when rust-common is updated

CI is currently broken for labrinth, however

* Fix theseus-release.yml to reference itself correctly

* Implement Labrinth side of tunneling

* Implement non-friend part of theseus tunneling

* Implement client-side except for socket loop

* Implement the socket loop

Doesn't work though. Debugging time!

* Fix config.rs

* Fix deadlock in labrinth socket handling

* Update dockerfile

* switch to workspace prepare at root level

* Wait for connection before tunneling in playground

* Move rust-common into labrinth

* Remove rust-common references from Actions

* Revert "Update dockerfile"

This reverts commit 3caad59bb474ce425d0b8928d7cee7ae1a5011bd.

* Fix Docker build

* Rebuild Theseus if common code changes

* Allow multiple connections from the same user

* Fix test building

* Move FriendSocketListening and FriendSocketStoppedListening to non-panicking TODO for now

* Make message_serialization macro take varargs for binary messages

* Improve syntax of message_serialization macro

* Remove the ability to connect to a virtual socket, and disable the ability to listen on one

* Allow the app to compile without running labrinth

* Clippy fix

* Update Rust and Clippy fix again
