     *
     *  - user is on /a
     *  - user clicks a link to /b
     *  - loader for /b redirects to /c
     *
     * In a non-JS app the browser would track the in-flight navigation to /b and
     * then replace it with /c when it encountered the redirect response.  In
     * the end it would only ever update the URL bar with /c.
     *
     * In client-side routing using pushState/replaceState, we aim to emulate
     * this behavior and we also do not update history until the end of the
     * navigation (including processed redirects).  This means that we never
     * actually touch history until we've processed redirects, so we just use
     * the history action from the original navigation (PUSH or REPLACE).

     *
     * One thing to note is that any Router-initiated Errors that make sense
     * to associate with a status code will be thrown as an ErrorResponse
     * instance which include the raw Error, such that the calling context can
     * serialize the error as they see fit while including the proper response
     * code.  Examples here are 404 and 405 errors that occur prior to reaching
     * any user-defined loaders.
     *
     * - `opts.routeId` allows you to specify the specific route handler to call.
     *   If not provided the handler will determine the proper route by matching
     *   against `request.url`
     * - `opts.requestContext` is an optional server context that will be passed
     *    to actions/loaders in the `context` parameter
