We sometimes return custom D-Bus errors. Right now those errors are ad-hoc, which means receivers don't have a proper way of checking whether a thrown GLib.Error corresponds to a particular remote error. In order to change that, we should define proper error enums and domains, and register them with GDBus, so that there is an automatic mapping between D-Bus errors and GLib.Errors. The new module doesn't export any domains or enums yet, but provides internal tooling to make these exports more convenient.
