 *  New: `MediaType.parameter()` gets a parameter like `boundary` from a media type like
    `multipart/mixed; boundary="abc"`.

 *  New: `Authenticator.JAVA_NET_AUTHENTICATOR` forwards authentication requests to

    Previously clones shared interceptors, which made it difficult to customize
    the interceptors on a request-by-request basis.
