 *  Fix: Don't leak a connection when a call is canceled immediately preceding the `onFailure()`
    callback.

 *  Fix: Apply call timeouts when connecting duplex calls, web sockets, and server-sent events.
    Once the streams are established no further timeout is enforced.

 *  Fix: Retain the `Route` when a connection is reused on a redirect or other follow-up. This was
