     * Internal method to send a request to the server.

 *  Fix: Always configure NPN headers. This fixes connectivity to
    `https://facebook.com` when SPDY and HTTP/2 are both disabled. Otherwise an
    unexpected NPN response is received and OkHttp crashes.
 *  Fix: Write continuation frames when HPACK data is larger than 16383 bytes.
 *  Fix: Don't drop uncaught exceptions thrown in async calls.
 *  Fix: Throw an exception eagerly when a request body is not legal. Previously
