In Hot Reloader we use `mod.resource.replace(/\\/g, '/').includes(key)`
to see if the module is the entry. However that `includes` check isn't
solid. Say the entry key is `app/path/page`, these will all be matched:
```
app/path/page.js
app/path/page.css
app/unrelated/app/path/page/another/page.js
```
This PR fixes that and added a test case. I'm unsure if this fixes the
newly reported cases in #43396.
fix NEXT-1110
Fixes: #43598
This was a tricky one to find! Not sure why more people aren't
complaining about this issue, was super annoying in my use case since
links had the wrong URL.
## What?
This issue only occurred when basepath was defined and middleware and
dynamic pages are being used.
Example from the reproduction repo mentioned in the issue tagged:
<img width="686" alt="Screenshot 2023-04-23 at 9 32 55 PM"
src="https://user-images.githubusercontent.com/11258286/233850968-e14f6b49-858b-410e-b8f9-93c90447090a.png">
## Why?
`nextConfig` wasn't passed to `getNextPathnameInfo` function, hence the
basePath wasn't removed from a intermediate variable and that trickled
down to cause this issue.
Added test case based on the issue reproduction repo

This ensures we use the proper body stream when rewriting to an external
resource as currently it tries to consume an already read body stream.
Fixes: https://github.com/vercel/next.js/issues/48040
This PR extends `invalid_server_react_dom_apis` with
`experimental_useOptimistic` and `experimental_useFormStatus` to create
early compile-time errors.
This ensures we properly strip conflicting headers from being forwarded
when handling the redirect request/response in actions.

This PR wraps the server patch dispatcher with a transition, we generally want all router dispatch to go through one
I'll follow up on tests properly later

## What?
Removes the empty `next.config.js` warning. Given that `create-next-app` now ships with an empty config with the type definition comment the warning is no longer needed.
## How?
Removed the warning, removed the tests.
Fixes NEXT-1107
## What?
Fixes a bug with iterating over the searchParams while `delete` and
`append` are used.
This is the minimal example of what happened:
```js
const searchParams = new URLSearchParams('a=valueA&b=valueB&c=valueC')
for(const key of searchParams.keys()) {
console.log(key)
if(key === 'b') {
searchParams.delete('b')
searchParams.append('bb', 'valueBB')
}
}
```
Output is:
```
a
b
bb
```
Instead of:
```
a
b
c
bb
```
The reason seems to be that the iterator uses an internal count while
iterating, e.g. the implementation in JavaScriptCore:
0743137c2f/Source/WebCore/html/URLSearchParams.cpp (L155-L163)
This can't be reproduced with `new Map()` or `new Set()`.
This PR fixes it by only iterating over the keys that are known before
the loop starts.

## What?
Removes `experimental.appDir` this was leftover from when I flipped the
switch.
Kept the config file as in the future we might add future flags and
such. It also helps that it has the types comment included so you always
get types.

This fixes an existing bug where there're Server Actions defined in both the "server" and "client" layers (client imported Actions). They have the same worker name as they exist in one route entry, but they're built into different modules and compiled differently (server and client layers). Because of that, each route entry can have 2 "action module entries".
This PR adds the logic to differentiate that via a "layer" field so they don't conflict.

### What?
This is a follow-up to https://github.com/vercel/next.js/pull/46290 by
@ijjk
Currently, nextjs build resolves provided incrementalCacheHandlerPath
over destDir (.next by default). And for standalone builds the custom
cache can't be resolved and leads to runtime error.
### Why?
This fix basically introduces support of incrementalCacheHandlerPath for
the standalone build.
### How?
incrementalCacheHandlerPath is now always resolved relatively to
distDir, which should work for both default and standalone builds.
Also, for convenience (and better testability)
incrementalCacheHandlerPath can now be provided as a relative path to
the project directory.
### What?
Fixes serving images that are referenced by JS files inside the `/app`
directory.
### Why?
### How?
The `NextImageContentSource` attempts to fetch the image out of it's
inner content source, and before we were only providing it with the
`/public` and `/pages` directory's respective sources.
