Fixes: #34342
Visiting the following page will call gSSP indefinitely in a loop and logs errors from `on-demand-entries-client`:
```js
const Home = () => null
export default Home
export function getServerSideProps() {
console.log("gssp called")
return { notFound: true }
}
```
We should not keep fetching the page if it returns 404 as it can introduce unnecessary data requests.

This PR removes the experimental `optimizeImages` flag. This feature was designed to automatically add preload tags for images, but I was never able to get it to do a very good job of selecting the images that actually need preloading.
This feature never graduated from experimental and in fact we never even publicized it as an experimental feature for people to try.
Additionally, even if someone was using this feature, it wouldn't have a functional effect, only a performance effect (removal of some preloads).
For those reasons, I believe it is safe to remove this functionality and that it is not a breaking change.
### Changes
* node server and webpack should share the same logic: auto detect react 18 and enable `reactRoot`
* fallback `_error` should use functional document if concurrent rendering is enabled
### Test
* Remove the hard code `reactRoot: true` in test suite
* Test some react-18 test suite with nodejs runtime
* Adding steps to build the app with docker in existing projects (without the need to create the app with the with-docker example)
* Update examples/with-docker/README.md

Related to #34185, this PR reduces the size of chunk that contains web-server.ts from 1.14mb to 210.8kb, by splitting base-http and api-utils into different environments.
Only affected thing is we can't have SSG preview mode for the web runtime via `getStaticProps`.

This PR ensures that the test "should render 500 error correctly" doesn't break when `runtime` is set to `nodejs` with `serverComponents` enabled.
This test case is now moved to the "basic" suite to ensure it doesn't break in both runtimes. And "should not bundle external imports into client builds for RSC" is enabled for the `nodejs` runtime too.

* Flight response should return `200` instead of `404` for 404 page
### Tests
* Run rsc for node runtime test suite

As per React 18 recommendation, we should use e.g. `renderToReadableStream` whenever we use `createRoot`. This is particularly important for currently supported suspense features like `React.lazy` to work properly during SSR.
However, unless you have opted in to streaming support (via [the `runtime` flag](https://github.com/vercel/next.js/pull/34068)), we will wait until `onCompleteAll` before sending it (via the `generateStaticHTML` flag).

Since we're always using `ReadableStream`, we should just get rid of `ResultPiper`.
This also lets us replace things like `bufferedReadFromReadableStream` with a `TransformStream` that does the same thing, so that it's `TransformStream`s all the way down.
Finally, we can get rid of the one-off call to `renderToReadableStream` and just use `renderToStream` whenever we're rendering a concurrent tree.
Instead of branching rendering based on Node.js and browser/web runtimes, we should just use the web version for now, which can run as-is on versions >=16.5.0 of Node.js, polyfilling `ReadableStream` on older versions when necessary.
There are a few potential downsides to this, as React is less able to optimize flushing and execution. We can revisit that in the future though if desired.

Cleans up the code of the middleware SSR loader and the web server. Currently the page components and render options are provided to the server via `globalThis` which is not ideal.
Instead we can inject `extendRenderOpts` and `loadComponent` to the web server. Since this is the the minimal mode and we'll need to handle `?flight` requests, we update the server render opts upon `updateRenderOpts` (In the future this should be changed to be passed to `requestHandler` to avoid race conditions).
Currently, we can't fully get rid of the `__server_context` global as we call `getBuildId` in the base server constructor.

This allows to have a more streamlined API for rewrites.
Since middlewares are code and not static configurations, we can allow people to
delete query params and not just overwrite them.
**⚠️ Warning ⚠️** this is a breaking change in query parameter behavior with middlewares, but the API will make more sense now. Compare the following:
```diff
import {NextResponse} from 'next/server'
export default function middleware({ nextUrl }) {
- nextUrl.searchParams.set('ignored-query-param', '');
+ nextUrl.searchParams.delete('ignored-query-param'); // 🎉
return NextResponse.rewrite(nextUrl);
}
```
Since this is breaking change, we're adding a warning every time we find a query param that is missing, and eventually--the warning will be deleted.
I don't think we need to worry about older versions of Next.js as the current behavior is misleading: merging query parameters make sense for static rewrites, but not for middlewares where you have access to all the query parameters and can manipulate them freely.

In the web runtime, currently we use `absolute500Path || absoluteErrorPath` to act like `/_error`. This PR fixes the behavior to use the `/pages/500.js` for 500 errors and `/pages/_error.js` for 500 fallback and other errors.

When an invalid image is requested, the 'finish' event is never triggered,
which ultimately leads to a 504 Gateway Timeout error.
This is fixed by invoking the 'callback' in `_write()`.

A few people including myself have been looking to use Relay with Next.JS and want to use the new Rust Compiler. This is my stab at an implementation.
### How it works?
Finds all `graphql` tagged template experssions and replaces them with `require`s to the file generated by Relay.
### Where I need help
- I've only worked with Rust a handful of times so I would appreciate any feedback on my use of language features.
- Is there any performance overhead to many duplicate usages of `require`? I imagine there's a cache in place but I want to be sure.
- I've added some unit tests & integration tests but I might be missing some use cases. Feel free to comment some use cases I'm not thinking about.
- [x] Related issues linked using `fixes #number`
- [x] Integration tests added
- [ ] Documentation added
- I haven't added any docs since this is an experimental API.
## Documentation / Examples
You're expected to be running the Relay Compiler along side Next.JS when you're developing. This is pretty standard. I wouldn't expect people to have any problem with this.
### Usage
In your `next.config.js`
```js
module.exports = {
experimental: {
relay: {
language: 'typescript', // or 'javascript`
artifactDirectory: 'path/to/you/artifact/directory' // you can leave this undefined if you did not specify one in the `relay.json`
}
}
}
```

(#31506 for context)
This PR implements the minimum viable web server on top of the Next.js base server, and integrates it into our middleware (edge) SSR runtime to handle all the requests.
This also addresses problems like missing dynamic routes support in our current handler.
Note that this is the initial implementation with the assumption that the web server is running under minimal mode. Also later we can refactor the `__server_context` environment to properly passing the context via the constructor or methods.

This fixes a case where optional catch-all route values aren't normalized to an array properly when the `index` value is passed. An additional test case has been added to prevent regressing on this.

Subtask of #31506
* move `serverBuildDir` and getter function of `publicDir` to next-server as only used place
* simplify `getMiddlewareInfo`, remove `distDir` and other params could be accessed from web server itself
Related to #31506, this PR adds `getPrerenderManifest` and `getRoutesManifest` methods to provide manifest files to the base server. In the future, we can consider making these methods async, or provide necessary manifests from the very top.
