* Add licences to all example/package.json that lack them
* Revert "Add licences to all example/package.json that lack them"
This reverts commit 5d4e25012f.
* Update check-examples to remove `license` field from examples
* Remove `license` from all examples.
This was mentioned in vercel/next.js#27121 but it looks like it didn't end up being in the merge?

Clean up package.json files in the `examples` directory:
- Add `private: true`
- Remove `version` (because they are irrelevant for packages that are not meant to be published)
- Remove `name` (because they are optional for packages that are not meant to be published, and when someone clones an example, they often rename it and the property becomes stale)
- Remove `author`
- Remove `description`
- Remove `license`
Also remove `with-dynamic-app-layout` example completely, since it does the same as `layout-component` (https://github.com/vercel/next.js/pull/27121#discussion_r668178408).
## Documentation / Examples
- [x] Make sure the linting passes
[With next 11 requiring react 17](https://nextjs.org/blog/next-11#upgrade-guide), most of the examples
need to be updated, so the following snippet updated all the examples to
a compatible react version.
```bash
cd examples/
fd -g 'package.json' | xargs sed -r -i 's/"react": ".*"/"react": "^17.0.2"/
fd -g 'package.json' | xargs sed -r -i 's/"react-dom": ".*"/"react-dom": "^17.0.2"/'
# exclude experimental react version
git checkout with-reason-relay/package.json
```
I wrote a [script](https://github.com/j0lv3r4/dependency-version-updater) to update dependencies recursively in `package.json` files, e.g.:
```
$ node index.js --path="./examples" --dependencies="react=^16.7.0,react-dom=^16.7.0"
```
This PR contains the result against the examples folder.
* Register the service worker.
* Update prefetcher code to do prefetching.
* Implement the core prefetching API.
support "import <Link>, { prefetch } from 'next/prefetch'"
* Implement a better communication system with the service worker.
* Add a separate example for prefetching
* Fix some typos.
* Initiate service worker support even prefetching is not used.
This is pretty important since initiating will reset the cache.
If we don't do this, it's possible to have old cached resources
after the user decided to remove all of the prefetching logic.
In this case, even the page didn't prefetch it'll use the
previously cached pages. That because of there might be a already running
service worker.
* Use url module to get pathname.
* Move prefetcher code to the client from pages
Now we also do a webpack build for the prefetcher code.
* Add prefetching docs to the README.md
* Fix some typo.
* Register service worker only if asked to prefetch
We also clean the cache always, even we initialize
the service worker or not.
