56389e81ff Abort Flight (#24754)
Add aborting to the Flight Server. This encodes the reason as an "error"
row that gets thrown client side. These are still exposed in prod which
is a follow up we'll still have to do to encode them as digests instead.

The error is encoded once and then referenced by each row that needs to
be updated.

dd4950c90e [Flight] Implement useId hook (#24172)
* Implements useId hook for Flight server.

The approach for ids for Flight is different from Fizz/Client where there is a need for determinancy. Flight rendered elements will not be rendered on the client and as such the ids generated in a request only need to be unique. However since FLight does support refetching subtrees it is possible a client will need to patch up a part of the tree rather than replacing the entire thing so it is not safe to use a simple incrementing counter. To solve for this we allow the caller to specify a prefix. On an initial fetch it is likely this will be empty but on refetches or subtrees we expect to have a client `useId` provide the prefix since it will guaranteed be unique for that subtree and thus for the entire tree. It is also possible that we will automatically provide prefixes based on a client/Fizz useId on refetches

in addition to the core change I also modified the structure of options for renderToReadableStream where `onError`, `context`, and the new `identifierPrefix` are properties of an Options object argument to avoid the clumsiness of a growing list of optional function arguments.

* defend against useId call outside of rendering

* switch to S from F for Server Component ids

* default to empty string identifier prefix

* Add a test demonstrating that there is no warning when double rendering on the client a server component that used useId

* lints and gates

4bc465a16f Rename Controls to PipeableStream (#24286)
This type isn't exported so it's technically not public.

This object mimics a ReadableStream.

Currently this is safe to destructure and call separately but I'm not sure
that's even guaranteed. It should probably be treated as a class in docs.

579c008a75 [Fizz/Flight] pipeToNodeWritable(..., writable).startWriting() -> renderToPipeableStream(...).pipe(writable) (#22450)
* Rename pipeToNodeWritable to renderToNodePipe

* Add startWriting API to Flight

We don't really need it in this case because there's way less reason to
delay the stream in Flight.

* Pass the destination to startWriting instead of renderToNode

* Rename startWriting to pipe

This mirrors the ReadableStream API in Node

* Error codes

* Rename to renderToPipeableStream

This mimics the renderToReadableStream API for the browser.

7843b142ac [Fizz/Flight] Pass in Destination lazily to startFlowing instead of in createRequest (#22449)
* Pass in Destination lazily in startFlowing instead of createRequest

* Delay fatal errors until we have a destination to forward them to

* Flow can now be inferred by whether there's a destination set

We can drop the destination when we're not flowing since there's nothing to
write to.

Fatal errors now close once flowing starts back up again.

* Defer fatal errors in Flight too

eba248c390 [Fizz/Flight] Remove reentrancy hack (#22446)
* Remove reentrant check from Fizz/Flight

* Make startFlowing explicit in Flight

This is already an explicit call in Fizz. This moves flowing to be explicit.

That way we can avoid calling it in start() for web streams and therefore
avoid the reentrant call.

* Add regression test

This test doesn't actually error due to the streams polyfill not behaving
like Chrome but rather according to spec.

* Update the Web Streams polyfill

Not that we need this but just in case there are differences that are fixed.

d1294c9d40 [Flight] Add global onError handler (#21129)
* Add onError option to Flight Server

The callback is called any time an error is generated in a server component.

This allows it to be logged on a server if needed. It'll still be rethrown
on the client so it can be logged there too but in case it never reaches
the client, here's a way to make sure it doesn't get lost.

* Add fatal error handling

5fd9db732d [Flight] Rename react-transport-... packages to react-server-... (#20403)
* Move files

* Update paths

* Rename import variables

* Rename /server to /writer

This is mainly because "React Server Server" is weird so we need another
dimension.

* Use "react-server" convention to enforce that writer is only loaded in a server
