Replace `url.parse` and `url.resolve` logic with whatwg `URL`, Bring in a customized `format` function to handle the node url objects that can be passed to router methods. This eliminates the need for `url` (and thus `native-url`) in core. Looks like it shaves off about 2.5Kb, according to the `size-limits` integration tests.
Currently following links are broken when using `basePath`:
```jsx
// pages/hello.js
<Link href="#hashlink">
<a id="hashlink">Hash Link</a>
</Link>
```
with `basePath: '/docs'`, this will navigate to `/docs/docs/hello#hashlink` instead of `/docs/hello#hashlink`
I have a further optimization that builds on this branch that removes `url.parse` and `url.resolve` in favor for `new URL()` in router and link. Will PR when this gets merged.
Convert `Link` to a function component. Prefetch logic and memoized url formatting now meshes nicely with React hooks. Class methods were hoisted to module scope to preserve performance characteristics.
* avoid pulling code in the bundle for `trailingSlash` logic when it's not enabled
* avoid cloning the url an extra time if normalizing the path doesn't change it
This updates `fetchNextData` to re-use the `getDataHref` function from `page-loader` which has more verbose handling to ensure the correct `/_next/data` URL is built. Re-using this logic ensures the `/_next/data` URL can still be built even when a mismatching `href` and `as` value is provided to `next/link`.
This also fixes a case in `getDataHref` where optional values that weren't provided would fail to build the data href since the check requiring the param be present while interpolating the route values hasn't been updated to allow missing params for optional values.
An additional test case has been added to the prerender suite to ensure the `/_next/data` URL is built correctly when mismatching `href` and `as` values are provided

* Avoid adding basePath when it's not needed
When using the `basePath` setting, on pages with params it will fire a router change. This will pass the url pathname in the `as` param using the `getUrl()` function. This means the `as` path will be sent through already including the `basePath`, leading to `/basePath/basePath/path` which will cause the router to throw an error.
* lint
* Add test case and ensure removal
* Make sure to re-add before changeState

Initial PR to make `next build` work with webpack 5, still needs more work to make sure runtimeChunk and such are shared between pages.
- No longer needs the custom ChunkNamesPlugin as the default behavior was changed
- Dropping AMP First client page bundles is now compatible
Noticed this while reviewing https://github.com/vercel/next.js/pull/14376. After having done https://github.com/vercel/next.js/pull/13699, this code didn't feel right to me:
```js
function prepareRoute(path: string) {
path = delBasePath(path || '')
// this /index rewrite is problematic, it makes pages/index.js
// and pages/index/index.js point to the same thing:
return toRoute(!path || path === '/' ? '/index' : path)
}
```
Added a nested index page to the prerender tests and found it was rendering the `/` route on navigation. This uncovered 2 more places around the dataroute where the index path was not translated correctly.
**edit:**
Just to note that there was nothing wrong with https://github.com/vercel/next.js/pull/14376, the issue was already there, I just noticed it while reading that PR
Saw in the client bootstrap script that the error message was printed alongside the stacktrace. This is unnecessary since the stacktrace already includes the error message. In fact, it seems like browsers already do a good job of printing an error with its stacktrace when you just print them using `console.error`. It's a bit minor, but this should shave off a few bytes of the bundle.
We previously used to remove our FOUC helper inside of the style injection to ensure content was shown as fast as possible.
This behavior, however, was problematic for a few reasons:
1. Large JavaScript chunks would take longer than an animation frame to parse, causing FOUC
1. Rendering would sometimes complete before an animation frame, causing improper effects
To fix the latter, we started removing the no FOUC helper **before** rendering, however, we never fixed the former by removing the dead code.
There's not a great way to test this because the FOUC is so fast and flaky, however, this code really shouldn't exist and isn't likely to be re-added (regress).
Also, we already have FOUC tests that occasionally flake, probably due to this.

Updates the way filenames are generated for browser compilation.
Notably:
- All entry bundles now have hashes in production, this includes pages (previously pages used a buildId in the path)
- The AmpFiles no longer depends on hardcoded bundle names, it uses the buildManifest instead (internals)
- All cases where we match the page name from the chunk/entrypoint name now use the same function `getRouteFromEntrypoint` (internals)
- In development we no longer include the "faked" `buildId` set to `development` for page files, instead we just use the `/_next/static/pages` path (was `/_next/static/development/pages`). This was changed as it caused unneeded complexity and makes generating the bundles easier (internals)
- Updated tons of tests to be more resilient to these changes by relying on the buildManifest instead of hardcoded paths (internals)

Initial work to use chunkhashes instead of buildid for the page files in production. This does not change the calculation of the filename itself initially.
As discussed, this streamlines the handling for `basePath` to not automatically strip and add the `basePath` when provided to `next/link` or `router.push/replace` and only automatically adds the `basePath` and when it is manually provided it will cause a 404 which ensures `href` still matches to the pages directory 1-to-1.
This also adds additional test cases that we discussed to ensure this behavior is working as intended

Fixes#13902
Disambiguate between pages/index.js and pages/index/index.js so that they resolve differently.
It all started with a bug in pagesmanifest that propagated throughout the codebase. After fixing pagesmanifest I was able to remove a few hacks here and there and more logic is shared now. especially the logic that resolves an entrypoint back into a route path. To sum up what happened:
- `getRouteFromEntrypoint` is the inverse operation of `getPageFile` that's under `pages/_document.tsx`
- `denormalizePagePath` is the inverse operation of `normalizePagePath`.
Everything is refactored in terms of these operations, that makes their behavior uniform and easier to update/patch in a central place. Before there were subtle differences between those that made `index/index.js` hard to handle.
Some potential follow up on this PR:
- [`hot-reloader`](https://github.com/vercel/next.js/pull/13699/files#diff-6161346d2c5f4b7abc87059d8768c44bR207) still has one place that does very similar behavior to `getRouteFromEntrypoint`. It can probably be rewritten in terms of `getRouteFromEntrypoint`.
- There are a few places where `denormalizePagePath(normalizePagePath(...))` is happening. This is a sign that `normalizePagePath` is doing some validation that is independent of its rewriting logic. That should probably be factored out in its own function. after that I should probably investigate whether `normalizePagePath` is even still needed at all.
- a lot of code is doing `.replace(/\\/g, '')`. If wanted, that could be replaced with `normalizePathSep`.
- It looks to me like some logic that's spread across the project can be centralized in 4 functions
- `getRouteFromEntrypoint` (part of this PR)
- its inverse `getEntrypointFromRoute` (already exists in `_document.tsx` as `getPageFile`)
- `getRouteFromPageFile`
- its inverse `getPageFileFromRoute` (already exists as `findPageFile ` in `server/lib/find-page-file.ts`)
It could be beneficial to structure the code to keep these fuctionalities close together and name them similarly.
- revise `index.amp` handling in pagesmanifest. I left it alone in this PR to keep it scoped, but it may be broken wrt nested index files as well. It might even make sense to reshape the pagesmanifest altogether to handle html/json/amp/... better
This removes remaining references to `granularChunks` in configs, error messages, and comments.
Also removed the `process.env.__NEXT_GRANULAR_CHUNKS` value.

Was going through _document and noticed some variable shadowing going on. Added a rule for it to our eslint configuration and went through all warnings with @Timer.
Next is currently removing useful information from the PnP error messages.
Before:
```
Module not found: Something that got detected as your top-level application (because it doesn't seem to belong to any package) tried to access a package that is not declared in your dependencies
```
After:
```
Module not found: Something that got detected as your top-level application (because it doesn't seem to belong to any package) tried to access a package that is not declared in your dependencies
Required package: foo (via "foo/components/Avatar")
Required by: /home/arcanis/foo/bar.tsx
```
This waits for the render to be committed to DOM before we render the route change complete event (no longer sync in new React).
We have tests that ensure this resolves.
