 *  Fix: Accept cookies for URLs that have an IPv6 address for a host.
 *  Fix: Don't log the protocol (HTTP/1.1, h2) in HttpLoggingInterceptor if the
    protocol isn't negotiated yet! Previously we'd log HTTP/1.1 by default, and
    this was confusing.
 *  Fix: Omit the message from MockWebServer's HTTP/2 `:status` header.
 *  Fix: Handle 'Expect: 100 Continue' properly in MockWebServer.
