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.

Part of #25028.
Our underlying read/write operations in `io` assume the buffer is a
Uint8Array, but we were passing in other typed arrays (in the case above
it was `Int8Array`).
There is no constructor code when creating an inspector `Session`
instance in Node. Also get rid of some symbols which should've been
private properties. This PR doesn't yet add any new implementations
though as these are mostly cosmetic changes.
For some reason we didn't register the `node:inspector` module, which
lead to a panic when trying to import it. This PR registers it.

This is commonly used to register loading non standard file types. But
some libs also register TS loaders which Deno supports natively, like
the npm `payload` package. This PR unblocks those.

- Return auth tag for GCM ciphers from auto padding shortcircuit
- Use _ring_ for ed25519 signing

This commit makes `fetch` error messages include source and destination TCP
socket info i.e. port number and IP address for better debuggability.
Closes #24922
This PR ensures that we forward a `rename` event in our file watcher.
The rust lib we use combines that with the `modify` event.
This fixes a compatibility issue with Node too, which sends the `rename`
event as well.

- **Key pair generation**
- Overhauled, but supported APIs unchanged
This PR adds a lot of new individual functionality. But most importantly
because
of the new key material representation, it is now trivial to add new
algorithms
(as shown by this PR).
Now, when adding a new algorithm, it is also widely supported - for
example
previously we supported ED25519 key pair generation, but we could not
import,
export, sign or verify with ED25519. We can now do all of those things.
I noticed
[`set_response_body`](ce42f82b5a/ext/http/service.rs (L439-L443))
was unexpectedly hot in profiles, with most of the time being spent in
`memmove`.
It turns out that `ResponseBytesInner` was _massive_ (5624 bytes), so
every time we moved a `ResponseBytesInner` (for instance in
`set_response_body`) we were doing a >5kb memmove, which adds up pretty
quickly.
This PR boxes the two larger variants (the compression streams),
shrinking `ResponseBytesInner` to a reasonable 48 bytes.

```ts
// hello-server.ts
Deno.serve((_req) => {
return new Response("Hello world");
});
// run with `deno run -A hello-server.ts`
// in separate terminal `wrk -d 10s http://127.0.0.1:8000`

So a nice ~15% bump. (With response body compression, the gain is ~10%
for gzip and neutral for brotli)
- upgrade to v8 12.8
- optimizes DataView bigint methods
- fixes global interceptors
- includes CPED methods for ALS
- fix global resolution
- makes global resolution consistent using host_defined_options.
originally a separate patch but due to the global interceptor bug it
needs to be included in this pr for all tests to pass.
