This PR implements the Node child_process IPC functionality in Deno on
Unix systems.
For `fd > 2` a duplex unix pipe is set up between the parent and child
processes. Currently implements data passing via the channel in the JSON
serialization format.
Part 2 of removing middleware.
This is somewhat awkward because `V8CrossThreadTaskSpawner` requires
tasks to be `Send`, but NAPI makes heavy use of `!Send` pointers. In
addition, Rust causes a closure to be `!Send` if you pull a `!Send`
value out of a struct.

Adds performance measurements for all ops used by the LSP. Also changes
output of "Language server status" page to include more precise
information.
Current suspicion is that computing "script version" takes a long time
for some users.
This problem occurred trying to load tensorflow.js
```
> import * as tf from 'npm:@tensorflow/tfjs';
Uncaught SyntaxError: Identifier 'mod' has already been declared at file:///Users/ry/Library/Caches/deno/npm/registry.npmjs.org/@tensorflow/tfjs/4.14.0/dist/tf.node.js:167:14

This commit adds a no-op flushHeaders method to the ServerResponse
object. It is a nop because the ServerResponse implementation is based
on top of the Deno server API instead of the Node `OutgoingMessage`
base.
Fixes #21509
This fixes #21434 for `BroadcastChannel` and `WebSocketStream`.
`--unstable` still enable both, but granular unstable flags now also
work:
* `--unstable-net` now enables `WebSocketStream`.
* `--unstable-broadcast-channel` now enables `BroadcastChannel`.
* Additionally, there are now tests for all granular unstable flags.
Since `unsafe-proto` already had tests, so I didn't add any for this
one.
It also introduces a map to keep track of granular unstable ids without
having to sync multiple places.
This significantly optimizes URLPattern in the case where the same
URL is matched against many patterns (like in a router).
Also minor speedups to other use-cases.
This commit brings back usage of primordials in "40_testing.js" by
turning it back into an ES module and using new "lazy loading" functionality
of ES modules coming from "deno_core".
The same approach was applied to "40_jupyter.js".

This PR is an attempt to fix
https://github.com/denoland/deno/issues/20293, in which node modules
connecting to databases fail due to TLS errors. I ran into this
attempting to use
[node-postgres](https://github.com/brianc/node-postgres) to connect to a
[Neon](https://neon.tech) database.
Investigating via `--inspect-brk` led me to notice that the hostname
eventually passed to `Deno.startTls` was null. The hostname is
determined by the following code:
f6b889b432/ext/node/polyfills/_tls_wrap.ts (L87-L89)
This logic doesn't appear to be correct. I couldn't find reference to
`servername` existing on the `secureContext` in either Node's or Deno's
docs. There's a lot of scope here, and it's my first time reading
through this code, so I could be missing something!
Node uses [the following
logic](2e458d9736/lib/_tls_wrap.js (L1679-L1682)
) to determine the hostname for certificate validation:
```
const hostname = options.servername ||
options.host ||
(options.socket && options.socket._host) ||
'localhost';
```
This PR updates the `TLSSocket` polyfill to use behave similarly (though
I omitted the default to `localhost` at the end; I'm not sure if
including it is necessary or correct). With this change, `node-postgres`
connects to my TLS endpoint successfully (aside: Neon requires SNI,
which also works as expected).

I tried to update the tests in
https://github.com/denoland/deno/blob/main/cli/tests/unit_node/tls_test.ts
to exercise this change, but the test fails for me on `main` on Linux. I
investigated briefly and noticed that the test fixture
`cli/tests/testdata/tls/localhost.crt` doesn't appear to include the
`subjectAltName` specified in `domains.txt`. I believe the certificate
isn't matching `localhost`, but that's where I ended investigating.
This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.
Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.
Adds an `--unstable-sloppy-imports` flag which supports the
following for `file:` specifiers:
* Allows writing `./mod` in a specifier to do extension probing.
- ex. `import { Example } from "./example"` instead of `import { Example
} from "./example.ts"`
* Allows writing `./routes` to do directory extension probing for files
like `./routes/index.ts`
* Allows writing `./mod.js` for *mod.ts* files.
This functionality is **NOT RECOMMENDED** for general use with Deno:
1. It's not as optimal for perf:
https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-2/
1. It makes tooling in the ecosystem more complex in order to have to
understand this.
1. The "Deno way" is to be explicit about what you're doing. It's better
in the long run.
1. It doesn't work if published to the Deno registry because doing stuff
like extension probing with remote specifiers would be incredibly slow.
This is instead only recommended to help with migrating existing
projects to Deno. For example, it's very useful for getting CJS projects
written with import/export declaration working in Deno without modifying
module specifiers and for supporting TS ESM projects written with
`./mod.js` specifiers.
This feature will output warnings to guide the user towards correcting
their specifiers. Additionally, quick fixes are provided in the LSP to
update these specifiers:
Landing changes required for
https://github.com/denoland/deno_core/pull/359
We needed to update 99_main.js and a whole load of tests.
API changes:
- setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler.
The function is now called from eventLoopTick.
- The promiseRejectMacrotaskCallback no longer exists, as this is
automatically handled in eventLoopTick.
- ops.op_dispatch_exception now takes a second parameter: in_promise.
The preferred way to call this op is now reportUnhandledException or
reportUnhandledPromiseRejection.
