 *  Fix: Don't use SPDY/3 style header concatenation for HTTP/2 request headers.
    This could have corrupted requests where multiple headers had the same name,
    as in cookies.

    `\0` would cause a late crash when building the request.
 *  Fix: Allow interceptors to change the request method.
