This serves to add support for [Subresource
Integrity](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity)
hashes for scripts added from the new app directory. This also has
support for utilizing nonce values passed from request headers (expected
to be generated per request in middleware) in the bootstrapping scripts
via the `Content-Security-Policy` header as such:
```
Content-Security-Policy: script-src 'nonce-2726c7f26c'
```
Which results in the inline scripts having a new `nonce` attribute hash
added. These features combined support for setting an aggressive Content
Security Policy on scripts loaded.

Follow-up to #37551
Implements prefetching for the new router.
There are multiple behaviors related to prefetching so I've split them out for each case. The list below each case is what's prefetched:
Reference:
- Checkmark checked → it's implemented.
- RSC Payload → Rendered server components.
- Router state → Patch for the router history state.
- Preloads for client component entry → This will be handled in a follow-up PR.
- No `loading.js` static case → Will be handled in a follow-up PR.
---
- `prefetch={true}` (default, same as current router, links in viewport are prefetched)
- [x] Static all the way down the component tree
- [x] RSC payload
- [x] Router state
- [ ] preloads for the client component entry
- [x] Not static all the way down the component tree
- [x] With `loading.js`
- [x] RSC payload up until the loading below the common layout
- [x] router state
- [ ] preloads for the client component entry
- [x] No `loading.js` (This case can be static files to make sure it’s fast)
- [x] router state
- [ ] preloads for the client component entry
- `prefetch={false}`
- [x] always do an optimistic navigation. We already have this implemented where it tries to figure out the router state based on the provided url. That result might be wrong but the router will automatically figure out that
---
In the first implementation there is a distinction between `hard` and `soft` navigation. With the addition of prefetching you no longer have to add a `soft` prop to `next/link` in order to leverage the `soft` case.
A heuristic has been added that automatically prefers `soft` navigation except when navigating between mismatching dynamic parameters.
An example:
- `app/[userOrTeam]/dashboard/page.js` and `app/[userOrTeam]/dashboard/settings/page.js`
- `/tim/dashboard` → `/tim/dashboard/settings` = Soft navigation
- `/tim/dashboard` → `/vercel/dashboard` = Hard navigation
- `/vercel/dashboard` → `/vercel/dashboard/settings` = Soft navigation
- `/vercel/dashboard/settings` -> `/tim/dashboard` = Hard navigation
---
While adding these new heuristics some of the tests started failing and I found some state bugs in `router.reload()` which have been fixed. An example being when you push to `/dashboard` while on `/` in the same transition it would navigate to `/`, it also wouldn't push a new history entry. Both of these cases are now fixed:
```
React.startTransition(() => {
router.push('/dashboard')
router.reload()
})
```
---
While debugging the various changes I ended up debugging and manually diffing the cache and router state quite often and was looking at a way to automate this. `useReducer` is quite similar to Redux so I was wondering if Redux Devtools could be used in order to debug the various actions as it has diffing built-in. It took a bit of time to figure out the connection mechanism but in the end I figured out how to connect `useReducer`, a new hook `useReducerWithReduxDevtools` has been added, we'll probably want to put this behind a compile-time flag when the new router is marked stable but until then it's useful to have it enabled by default (only when you have Redux Devtools installed ofcourse).
> ⚠️ Redux Devtools is only connected to take incoming actions / state. Time travel and other features are not supported because the state sent to the devtools is normalized to allow diffing the maps, you can't move backward based on that state so applying the state is not connected.
Example of the integration:
<img width="1912" alt="Screen Shot 2022-09-02 at 10 00 40" src="https://user-images.githubusercontent.com/6324199/188637303-ad8d6a81-15e5-4b65-875b-1c4f93df4e44.png">
This addresses a bug where invoking `next dev` or `next start` with `--port 0` would fall back to the default port of 3000 instead of binding to port 0 (which typically results in the operating system assigning a free port).
I couldn't find a straightforward way of adding a test for next-start. It looks like we could add a similar test as for dev, but would need to generate a built project to serve.
Manual test plan for `next start`:
```
$ ./packages/next/dist/bin/next start --port 0
ready - started server on 0.0.0.0:53508, url: http://localhost:53508
```

This PR fixes an issue where tests fail because the generated tmp directory already exists. This is likely caused from two tmp dirs being generated in the same millisecond.
```

errno: -17,

This adds handling for prefetching `onTouchStart` as this gives a little more time to start parsing required scripts for a page transition if not already done that can help make the transition faster. This is based on research showing the touch start event firing on average `90ms` before click (x-ref: [source](https://instant.page/#:~:text=in%20the%20world.-,On%20mobile,-A%20user%20starts))
This also adds testing safari with playwright so we can run these in PRs instead of only after merge and adds initial mobile testing as well.

Fixes: https://github.com/vercel/next.js/issues/38783
Client components might result in a page chunk or a standalone splitted chunk marked in flight manifest, this PR filters out the page chunk for standalone chunk so that while loading a client chunk (like for `next/link`) it won't load the page chunk to break the hydration. `chunk.ids` is not enough for getting required chunks, so we get the chunks from chunk group then filter the required ones.

Previously we use custom webpack alias for specific react versions for non server side node runtime aliases. This PR alias the entire folders of `react/` and `react-dom/` so that no more alias in next.config is required but only the nodejs require hook.
* Alias `react` and `react-dom` by default
* Use `react@experimental` to run server components integration test
* Drop with-react-17 test util, add `__NEXT_REACT_CHANNEL` as an env var for testing and development to specify the react channel is 17 or new experimental version
This ensures we properly alias and internalize `@swc/helpers` so that we don't rely on package managers hoisting this dependency for the build to work properly. This also disables the external helpers with `jest` as this can also require hoisting to work and doesn't provide as much of an optimization.

If you end up in a state where an error happened and you also should be warned about a full refresh - you get stuck. The full refresh is blocked by the warning but the error is shown instead.
Tests didn't catch this because the refresh warning never showed in `__NEXT_TEST_MODE`.

## What's in there?
Partially fixes https://github.com/vercel/edge-functions/issues/82
Relates to #36715
Our webpack plugin for middleware leverages static analysis to detect Dyanamic code evaluation in user `_middleware.js` file (and depedencies). Since edge function runtime do not allow them, the build is aborted.
The use of `Function.bind` is considered invalid, while it is legit. A customer using `@aws-sdk/client-s3` reported it.
This PR fixes it.
Please note that this check is too strict: some dynamic code may be in the bundle (despite treeshaking), but may never be used (because of code branches). Since this point is under discussion, this PR adds tests covering some false positives (`@apollo/react-hook`, `qs` and `has`), but does not change the behavior (consider them as errors).
## Notes to reviewer
I looked for test facilities allowing to download the required 3rd party modules. `createNext()` in production context made my day, but showed two issues:
- `cliOutput` is not cleaned in between tests. While clearance during `stop()` would be annoying, I hope that clearance during `start()` is better.
- if `start()` fails while building, the created instance can never be stopped. This is because we don't clear `childProcess` after `build`.

Follow-up to https://github.com/vercel/next.js/pull/36527 this adds falling back to the wasm swc build when loading the native bindings fails so that we don't block the build on the native dependency being available.
This continues off of https://github.com/vercel/next.js/pull/33496 but does not add a postinstall script yet and only downloads the fallback when the native dependency fails to load.
Fixes#35469
Adds `pagesDir` which is required for the Relay transform.

This adds a new test mode `next-deploy` which allows testing against deployments using the Vercel CLI. After running these tests they uncovered some bugs we need to correct before fully enabling. Patching the uncovered issues will be done in follow-up PRs and then after resolved this will be enabled to run after new publishes.
Tests that uncovered bugs to patch in follow-ups:
- [ ] test/e2e/getserversideprops/test/index.test.ts (req.url normalizing)
- [ ] test/e2e/i18n-api-support/index.test.ts (locale prefixed API routes matching)
- [ ] test/e2e/prerender.test.ts (/_next/data/build-id/ does not 404)
Fixes https://github.com/vercel/next.js/issues/33578
This PR fixes `Link` component as well to not add locale for api routes since both preflight redirect and link should work the same.

To collect the requests starting from page load, we need to register event listeners before page loading (`page.goto` API invocation). By default webdriver will wait for hydration, so we need to register events inside `browser.loadPage` to ensure we can collect the requests before hydration is done.
### Changes
* Add `beforePageLoad` for next webdriver
* registry page `'request'` event before loading page
* update related tests for agruments change
### Usage
```js
browser = await webdriver(appPort, '/path', {
waitHydration, // default true
retryWaitHydration, // default false
disableCache, // default false
beforePageLoad, // default undefined
})
```

In PR #26968, we added Set of loaded images that was removed in #33474 erroneously.
We still need to track loaded images since we can't rely on `img.complete`, especially if the parent uses `react-virtualized`.
Tested on https://nextjs.org/showcase
This fixes our check for fallback pages during `next export` as we are currently erroring even when the erroneous pages are not included in the `exportPathMap`. This also adds additional tests to certify the expected behavior for the error.
