Initial import of OTEL code supporting tracing. Metrics soon to come.
Implements APIs for https://jsr.io/@deno/otel so that code using
OpenTelemetry.js just works tm.
There is still a lot of work to do with configuration and adding
built-in tracing to core APIs, which will come in followup PRs.

```js
Deno.serve(async (req) => {
const { promise, resolve } = Promise.withResolvers<void>();
req.signal.addEventListener("abort", () => {
resolve();
});
await promise;
return new Response("Ok");
});
```

Closes https://github.com/denoland/deno/issues/21653

Fixes https://github.com/denoland/deno/issues/26341.
We try to call `op_set_nodelay` on an `UpgradeStream`, which doesn't
support that operation.
|
|
Aligns the error messages in the ext/http and a few messages in the
ext/fetch folder to be in-line with the Deno style guide.
This change-set also removes some unnecessary checks in the 00_serve.ts.
These options were recently removed, so it doesn't make sense to check
for them anymore.

Closes #24099

This PR fixes an invalid URL being printed when running `deno serve`
Before: invalid URL
```sh
$ deno serve --host localhost
deno serve: Listening on http://::1:8000/
```
After: valid URL
```sh
$ deno serve --host localhost
deno serve: Listening on http://[::1]:8000/
```

This commit changes when to cause the hostname substition of `0.0.0.0` ->
`localhost`.
Currently we substitute `localhost` to the hostname on windows before
calling `options.onListen`, which prevents the users to do more advanced
thing using hostname string like
https://github.com/denoland/std/issues/5558. This PR changes it not to
substitute it when the user provide `onListen` callback.
closes #24776

To ensure consistency across the codebase, this commit refactors the
code in the `ext` folder to use `throw new Error`` instead of `throw`
for throwing errors.

Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

Prior to this commit, you could return a `Response` created from a
string or Uint8Array multiple times.
Now you can't do that anymore.

Max rps without a signal is unchanged, however we can drastically reduce
memory usage by not creating the signal until needed, and we can
optimize the rps in the case where the signal is created.
With a quick memory benchmark, it looks like this helps pretty
drastically with # of GCs when benchmarking w/wrk:

By default, `deno serve` will assign port 8000 (like `Deno.serve`).
Users may choose a different port using `--port`.
`deno serve /tmp/file.ts`
`server.ts`:
```ts
export default {
fetch(req) {
return new Response("hello world!\n");
},
};
```
|
|
When the response has been successfully send, we abort the
`Request.signal` property to indicate that all resources associated with
this transaction may be torn down.
