 *  Fix a bug in `Content-Length` reporting for gzipped streams in the Apache
    HTTP client adapter. (thanks kwuollett)
 *  Work around the Alcatel `getByInetAddress` bug (thanks k.kocel)
 *  Be more aggressive about testing pooled sockets before reuse. (thanks
    warpspin)
 *  Include `Content-Type` and `Content-Encoding` in the Apache HTTP client
    adapter. (thanks kwuollett)
 *  Add a media type class to OkHttp.
 *  Change custom header prefix:

   *   iPAddress                       [7]     OCTET STRING,
   *   registeredID                    [8]     OBJECT IDENTIFIER
   * }
   * ```
   *
   * The first property of the pair is the adapter that was used, the second property is the value.
