* Utility function to handle redirects returned from an action or loader.
* Normally, a redirect "replaces" the navigation that triggered it. So, for
* example:
*
* - 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).

/**
* The query() method is intended for document requests, in which we want to
* call an optional action and potentially multiple loaders for all nested
* routes. It returns a StaticHandlerContext object, which is very similar
* to the router state (location, loaderData, actionData, errors, etc.) and
* also adds SSR-specific information such as the statusCode and headers
* from action/loaders Responses.
*
* It _should_ never throw and should report all errors through the
* returned context.errors object, properly associating errors to their error
* boundary. Additionally, it tracks _deepestRenderedBoundaryId which can be
* used to emulate React error boundaries during SSr by performing a second
* pass only down to the boundaryId.
*
* The one exception where we do not return a StaticHandlerContext is when a
* redirect response is returned or thrown from any action/loader. We
* propagate that out and return the raw Response so the HTTP server can
* return it directly.
*
* - `opts.requestContext` is an optional server context that will be passed
* to actions/loaders in the `context` parameter
* - `opts.skipLoaderErrorBubbling` is an optional parameter that will prevent
* the bubbling of errors which allows single-fetch-type implementations
* where the client will handle the bubbling and we may need to return data
* for the handling route

* The queryRoute() method is intended for targeted route requests, either

* returned value directly. In most cases, this will be a Response returned
* from the action/loader, but it may be a primitive or other value as well -
* and in such cases the calling context should handle that accordingly.
*
* We do respect the throw/return differentiation, so if an action/loader
* throws, then this method will throw the value. This is important so we
* can do proper boundary identification in Remix where a thrown Response
* must go to the Catch Boundary but a returned Response is happy-path.
*
* 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
