The function was extremely messy in that it, depending on the set of arguments, it could either modify the Connection object in `this` or not. It had a lot of arguments, with each call site passing a different combination of null values. This PR: - packs "url" and "comm_fd" arguments into a variant as they are mutually exclusive - removes the (surprising) "null url *and* null comm_fd" code path which is not used as of https://github.com/llvm/llvm-project/pull/145017 - marks the function as `static` to make it clear it (now) does not operate on the `this` object. Depends on #145017
