 /// A wrapper around [HttpServer] that swallows errors caused by requests
 /// behaving badly. This provides the following guarantees:
 ///
 /// * The [SafeHttpServer.listen] onError callback will only emit server-wide
 ///   errors. It will not emit errors for requests that were unparseable or
 ///   where the connection was closed too soon.
 /// * [HttpResponse.done] will emit no errors.
 ///
 /// The [HttpRequest] data stream can still emit errors.
