This adds ncc inlining optimizations for the following dependencies:
* cacache
* schema-utils
* find-cache-dir
* mkdirp
* neo-async
* web-vitals
The slight increase in output in the reports here is due to the variation of the bundled version of web-vitals.
In addition, this moves ast-types to be a devDependencies entry instead of in dependencies as it was before https://github.com/vercel/next.js/pull/14746 as I could not see any production usage (ping @prateekbh). Happy to separate that out into a separate PR if preferred too.
This PR prints a pretty error when the Image `src` property is a [protocol-relative URL](https://www.paulirish.com/2010/the-protocol-relative-url/).
> Update 2014.12.17:
> Now that SSL is encouraged for everyone and doesn’t have performance concerns, this technique is now an anti-pattern. If the asset you need is available on SSL, then always use the https:// asset.
Fixes#18536
Next.js would try to "recover" if its CSS assets went missing (i.e. a deployment occured) **while the page was initially loading**.
This handled a rare case where we'd try to let the Next.js complete hydrating even though a deployment occured.
However, in practice, this never worked: if the `fetch()` failed, that means the original assets never downloaded themselves (because the `fetch()` should be coming from disk cache).
Instead of letting Next.js get itself into a weird state, let's just stop hydration so that the page doesn't accidentally delete its styles.
The handle-no-styles behavior is already tested in `test/integration/css/test/index.test.js`. There was never a branch for it using its cached styles, so nothing else needs updated.

Fixes#17930
When visiting a non-locale prefixed path (`/hello` instead of `/fr/hello`) we don't trigger locale redirects currently so if another locale is matched we need to ensure this is reset to the `defaultLocale` for rendering to prevent a mis-match on the client and the server.
This also fixes hydration errors from occurring with `asPath` for `getServerSideProps` pages due to `normalizeLocalePath` expecting only a pathname and `asPath` containing `hash` and `query values also.

This PR deprecates the `unsized` property from NextImage because the property did not accomplish the desired effect.
Users should rely on one of the new layouts instead:
- `<Image layout="fixed" />`
- `<Image layout="intrinsic" />`
- `<Image layout="responsive" />`
- `<Image layout="fill" />`
The `unsized` property will continue to work as-is in production but is deprecated and will throw in dev.

### TODO:
- [x] test `layout=fill` in typescript types
- [x] test `layout=fill` render behavior
- [x] test that `unsized` switches to `layout=fill`
- [x] test `next dev` erroring on `unsized`
- [ ] layout docs (tracked in issue #18554)
- [ ] both `layout=fill` and `layout=responsive` use all deviceWidths in the srcset

This PR introduces a new `layout` property.
This allows 3 possible values (`fixed`, `intrinsic`, or `responsive`) which solve many use cases we have seen since 10.0.0 and will hopefully avoid usage of `unsized`.

This does two things:
- Rename `iconSizes` to `imageSizes`.
- Give priority to `imageSizes` regardless of `deviceSizes` as a means to opt-out of the srcset behavior.
This separates the `next.config.js` property `images.sizes` into to properties: `images.deviceSizes` and `images.iconSizes`.
The purpose is for images that are not intended to take up the majority of the viewport.

There was a bug when the user defines a width on the Image component, but a larger size image is requested.
This is because the browser uses the `srcset` to decide which image size to request and we had the srcset basically hardcoded.
This PR fixes the behavior so that the `srcset` will never be larger than the `width` defined on the component.
It also fixes a bug where the preload srcset did not match the img srcset.

For many users refactoring from `<img>` to `<Image>`, we can often support their properties as-is.
The exception was width/height.
This PR allows the `<Image>` component to accept strings for `width` and `height` just like `<img>`.
Related to #18122
This PR updates the `<Image>` component to follow the same property naming as native `<img>`.

This currently allows two values,`loading=lazy` and `loading=eager`, but there might be new values added in a future spec.

This makes sure that we detect the correct default locale for domain specific locales since a domain can have a different default locale residing at the root and we need to check this on the client for prerendered/auto-static pages. This also makes sure we disable the built-in redirect handling when on Vercel since it's handled already.
Tests for this are tricky since we need to load the browser with a custom domain which requires editing the host file. Existing tests should ensure this doesn't break non-domain specific locale behavior though. This was also tested manually while testing https://github.com/vercel/vercel/pull/5298

This PR adjust the Web Vitals reporting to be called *after* rendering occurs. It used to work like this, but React's render method is no longer synchronous—so we have to do it in an effect.
Existing tests should cover this code path, and IMO it's unfeasible to test that it's invoked _after_ hydration.
Also removed the `&& ST` condition which is not relevant to Web Vitals.
This adds the `locale` prop for `next/link` to allow transitioning between locales client-side and also allows passing the locale to `router.push/replace` via the transition options similar to `shallow` e.g. `router.push('/another', '/another, { locale: 'nl' })`

While working on https://github.com/vercel/next.js/pull/17755 noticed a couple of cases that needed fixing and broke them out to this PR to make that one easier to review. One fix is for `ssgCacheKey` where it wasn't having the `locale` prefix stripped correctly due to the locales no longer being populated under the server instances `renderOpts` and the second fix is for the `asPath` not being set to `/` when the `locale` is the only part in the URL e.g. `/en` became an empty string `""`
