* Rename types: * `ptr` types have no suffix (e.g. `ClientP` -> `Client`) * normal object types hyve a `T` suffix, if needed (e.g. `Port` -> `PortT`) * Constants also use CamelCase (UPPER_CASE can still be used). * Make functions returning an error discardable * Add missing return types for some functions.
