Fixes: https://github.com/vercel/next.js/issues/27888
Our `Observable` use has gotten sufficiently complex that it makes sense to just use a 3rd party implementation and not worry about maintaining it ourselves. As a bonus, it doesn't rely on Node APIs.
Add `-js` `-ts` `-tsx` `-css` to `build-module` in traces to allow for easier filtering.

Removes the extra webpack handling that was previously done, this ensures the file which is already minified and compiled does not get passed through minification again.

The polyfill loading already has tests so no other changes are necessary.

Adds `RenderResult`, replacing the `string` that `renderToHTML` used to return, with an `Observable`-like API that callers can use to subscribe and get a callback when chunks are available to flush, etc.
This is the last architectural change needed for streaming. There are, however, other things currently standing in the way of streaming. For example, it is common to mutate `res` in `getServerSideProps` to do routing work, or write headers, before fetching page data. This pattern effectively nullifies any advantages of streaming. I may do a follow-up PR that adds an experimental alternative for applications not using React 18, but the main purpose for this support is for Suspense and Server Components.
For that reason, there's no actual streaming here yet: instead we just flush a single chunk. A follow-up PR will add support for streaming suspense boundaries in React 18.

Currently there is a lot of mutation in the Next.js Server and the checks for Locale are directly coded in the general request handler. Ideally, we should have a function where we just pass the request input (url + headers + config) and generate a bunch of metadata that analyzes it generating all metadata we might require for both the URL and i18n + basePath information.
This PR brings:
- A new parsing function `parseUrl` that joins parsing an absolute/relative URL into a data structure compatible with the Node parsing output but missing redundant properties.
- A wrapper `parseNextURL` that extends `parseUrl` analyzing `i18n` and `basePath` based on the provided configuration, url and headers. This function is pure and stateless so it can be used outside of the Next.js context.
- Types improvements and reuse.
- Refactors `next-server.ts` request handling using the above mentioned functions so that the code there just apply effects to the `req` object and the `parsedUrl.query` leaving the code much more straightforward.
- Refactors `getRouteRegex` decomposing in two different functions where `getParametrizedRoute` can be used to retrieve the serializable data that is used to generate the Regex.
when typechecking next.config.js as described [in the docs](https://github.com/vercel/next.js/blob/canary/docs/basic-features/typescript.md#type-checking-nextconfigjs), an error would be thrown if `future` and `experimental` are missing. When using `Partial<>` in the type definition instead, it works as expected.

log a warning for hanging jobs
#### add page generation duration to summary tree
for `[+n more pages]` is will show `(avg 321 ms)` when the average is over the threshold.
It will allocate 8 lines for preview pages (instead of 4) when they contain slow pages

This updates redirects' regexes to not match `/_next` paths since this is currently unexpected and can easily cause a multi-match redirect to break loading client-side assets. This also fixes custom-routes not matching correctly when `trailingSlash: true/false` is used

This adds some missing fields to the `NextConfig` type we expose under `next` and also adds a `NextConfigComplete` internal type that allows us to not treat all fields as optional like you would when using the type in `next.config.js`.

This PR changes the implementation of `placeholder=blur` when using `next dev` so that it lazy loads on-demand.
This will improve the developer experience for web apps with many blurred images.

cjs package: Offers only CJS implementation (may not even have an `exports` field)
mixed package: Offers CJS and ESM implementation via `exports` field
pure esm package: Only offers an ESM implementation (may not even have an `exports` field)
pure cjs package: CommonJs package that prevents importing via `exports` field when `import` is used.
`*` This case will behave a bit unexpected for now, since `require` will return a Promise. So that need to be awaited. This will be fixed once the whole next.js bundle is ESM. It didn't work at all before this PR.
`**` This is a new Error when trying to require an esm package.
`***` For mixed packages we prefer the CommonJS variant to avoid a breaking change.

fixes#26607
This change makes it so the image loader plugin only emits a file while processing an image import for the client. The final generated image URL was already the same in SSR and CSR anyway, so this change doesn't have any functional impact.
I also changed the name of the static page in the image component tests, since it was causing some conflicts with the static assets folder.

This PR does a couple things:
1. Omit svg static imports if the user has defined custom webpack config with svg rule
2. Change TS type to `any` for svg imports to avoid conflicts with other plugins
The idea is that some users want to use `next/image` with static imports for most image types but not for svg and instead inline those images with a plugin.

Also logs a message when defaulting, and a warning when using a prerelease build of `react-dom` (e.g. the React 18 alpha) which are not officially supported.
Note: I've done this in `webpack-config.ts` instead of the Next.js config, as we don't actually want you to be able to opt-out *without* downgrading back to React 17, and so it ought to be entirely removed from the config eventually.

Fixes: https://github.com/vercel/next.js/issues/26163
- Enables excludeDefaultMomentLocales by default
- Adds distDir cleaning (See RFC #6009)
- Adds support for `PORT`
- Removes `router.events` from the server-side router as it should not be used server-side (long-standing todo that is potentially breaking). Note that it's still available as `Router.events` (import Router from 'next/router') and with `useRouter` in `useEffect`. Using it with `useEffect` is the correct way and I've updated the upgrading guide to reflect that
- Added webpack 5 to the upgrading guide
- Removed `Head.rewind` as it's been a no-op since Next.js 9.5 and can now be safely removed from user code

There are strict conditions for using `placeholder=blur` documented in #25949 but this will give the user a better understanding during `next dev` and links to the error.
- Error when `placeholder=blur` and no `blurDataURL`
- The Error for small images with `placeholder=blur` has been changed to a warning
- Added support for blurring a webp image
- Added error page linking to relevant docs
Fixes an issue where "env" would be ignored and would crash if there was no top level "presets". Also found that webpack did not invalidate the cache on changes to the babel config, so I also fixed that.
