partially unblocks #25470
This PR aligns the resolution of `localhost` hostname to Node.js
behavior.
In Node.js `dns.lookup("localhost", (_, addr) => console.log(addr))`
prints ipv6 address `::1`, but it prints ipv4 address `127.0.0.1` in
Deno. That difference causes some errors in the work of enabling
`createConnection` option in `http.request` (#25470). This PR fixes the
issue by aligning `dns.lookup` behavior to Node.js.
This PR also changes the following behaviors (resolving TODOs):
- `http.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
- `net.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
These changes are also alignments to Node.js behaviors.

There were a handful of bugs here causing the hang (each with a
corresponding minimized test):
- We were canceling recv futures when `receiveMessageOnPort` was called,
but this caused the "receive loop" in the message port to exit. This was
due to the fact that `CancelHandle`s are never reset (i.e., once you
`cancel` a `CancelHandle`, it remains cancelled). That meant that after
`receieveMessageOnPort` was called, the subsequent calls to
`op_message_port_recv_message` would throw `Interrupted` exceptions, and
we would exit the loop.
The cancellation, however, isn't actually necessary.
`op_message_port_recv_message` only borrows the underlying port for long
enough to poll the receiver, so the borrow there could never overlap
with `op_message_port_recv_message_sync`.
- Calling `MessagePort.unref()` caused the "receive loop" in the message
port to exit. This was because we were setting
`messageEventListenerCount` to 0 on unref. Not only does that break the
counter when multiple `MessagePort`s are present in the same thread, but
we also exited the "receive loop" whenever the listener count was 0. I
assume this was to prevent the recv promise from keeping the event loop
open.
Instead of this, I chose to just unref the recv promise as needed to
control the event loop.
- The last bug causing the hang (which was a doozy to debug) ended up
being an unfortunate interaction between how we implement our
messageport "receive loop" and a pattern found in `npm:piscina` (which
angular uses). The gist of it is that piscina uses an atomic wait loop
along with `receiveMessageOnPort` in its worker threads, and as the
worker is getting started, the following incredibly convoluted series of
events occurs:
1. Parent sends a MessagePort `p` to worker
2. Parent sends a message `m` to the port `p`
3. Parent notifies the worker with `Atomics.notify` that a new message
is available
4. Worker receives message, adds "message" listener to port `p`
5. Adding the listener triggers `MessagePort.start()` on `p`
6. Receive loop in MessagePort.start receives the message `m`, but then
hits an await point and yields (before dispatching the "message" event)
7. Worker continues execution, starts the atomic wait loop, and
immediately receives the existing notification from the parent that a
message is available
8. Worker attempts to receive the new message `m` with
`receiveMessageOnPort`, but this returns `undefined` because the receive
loop already took the message in 6
9. Atomic wait loop continues to next iteration, waiting for the next
message with `Atomic.wait`
10. `Atomic.wait` blocks the worker thread, which prevents the receive
loop from continuing and dispatching the "message" event for the
received message
11. The parent waits for the worker to respond to the first message, and
waits
12. The thread can't make any more progress, and the whole process hangs
The fix I've chosen here (which I don't particularly love, but it works)
is to just delay the `MessagePort.start` call until the end of the event
loop turn, so that the atomic wait loop receives the message first. This
prevents the hang.
---
Those were the main issues causing the hang. There ended up being a few
other small bugs as well, namely `exit` being emitted multiple times,
and not patching up the message port when it's received by
`receiveMessageOnPort`.
Testing once again if the crates are being properly released.

Add an implementation of cpu_info() for OpenBSD, that returns a
correctly-sized array. Since Rust's libc bindings for OpenBSD do not
contain all symbols necessary for a full implementation and it is not
planned to add them, this solution at least avoids problems with code
that relies on cpu_info() purely for the size of the returned array to
derive the number of available CPUs.

- Swapped `Object.assign` for `ObjectAssign` primordial.
- Removed referencing TODO comment.
Please disregard if no longer desired.
Apparently `path/posix` and `path/win32` have circular exports. I do not
know why.
Additionally there's a deprecated function `_makeLong` which is just
`toNamespacedPath`

A workaround for the issue #25480
`Deno.Listener` can't be closed synchronously after `accept()` is
called. This PR delays the `accept` call 2 ticks (The listener callback
is called 1 tick later. So the 1 tick delay is not enough), and makes
`net.Server` capable of being closed synchronously.
This unblocks `npm:detect-port` and `npm:portfinder`
closes #18301

Ended up being a larger refactoring, since we're now juggling
(potentially) two config files in the same `add`, instead of choosing
one. I don't love the shape of the code, but I think it's good enough
Some smaller side improvements:
- `deno remove` supports `jsonc`
- `deno install --dev` will be a really simple change
- if `deno remove` removes the last import/dependency in the
`imports`/`dependencies`/`devDependencies` field, it removes the field
instead of leaving an empty object
This commit adds:
- `addAbortListener` in `node:events`
- `aborted` in `node:util`
- `execPath` and `execvArgs` named export from `node:process`
- `getDefaultHighWaterMark` from `node:stream`
The `execPath` is very hacky - because module namespaces can not have
real getters, `execPath` is an object with a `toString()` method that on
call returns the actual `execPath`, and replaces the `execPath` binding
with the string. This is done so that we don't require the `execPath`
permission on startup.
This change fixes the handling of upgraded socket from `node:http` module.
In `op_node_http_fetch_response_upgrade`, we create DuplexStream paired
with `hyper::upgrade::Upgraded`. When the connection is closed from the
server, the read result from `Upgraded` becomes 0. However because we
don't close the paired DuplexStream at that point, the Socket object in
JS side keeps alive even after the server closed. That caused the issue
#20179
This change fixes it by closing the paired DuplexStream when the
`Upgraded` stream returns 0 read result.

Turns out we only virtualized it so one could have a `Console` property,
and the other one not. We can just make this `console.Console` available
everywhere.
Fixes #23281. Part of #20613.
We were emitting the `online` event in the constructor, so the caller
could never receive it (since there was no time for them to add a
listener). Instead, emit the event where it's intended – after the
worker is initialized.

After this parcel no longer freezes, but still will fail due to other
bugs (which will be fixed in other PRs)
- Add missing exports to `node:cluster`
- Fix default export not being an instance of `EventEmitter`
- Fix aliasing of properties
- Fix `disconnected` -> `disconnect` export naming
This makes `log4js` work in Deno. `karma` starts too, but somehow the
server isn't responding. That looks like a different issue.

This commit gets deno_node's customizer to use fixed-length array
instead of `Vec` to avoid wrong capacity allocation.
In the previous code we reserve a capacity of 14 for
`external_references`. However, after pushing all the necessary
`ExternalReference`s, it ends up with a length of 21, not 14. This means
another allocation happens even though we reserve some space.
To make sure that there will no longer be extra allocation, it should be
a good idea to use fixed-length array here.
This commit bumps the minimum required version of `dsa` crate to 0.6.3.
This is preferable because `SigningKey::sign_prehashed_rfc6979` function
we use in `deno_node` is available from this version.

This PR addresses a regression introduced in
https://github.com/denoland/deno/pull/25021 that would cause the
`req.url` parameter in Node's http server to always be a single
character instead of the expected value. The regression was caused by
effectively calling `.indexOf()` on an empty string and thus passing the
wrong index for slicing.
```js
"".indexOf("/") // -> -1
request.url.slice(-1) // effectively only giving us the last character
```

PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
59e5a34713/prism.js (L11)
Now the detection logic above is broken when it's imported from Deno's
Web Worker context because we only hide `self` (Prism assumes when
`WorkerGlobalScope` is available, `self` is also available).
This change fixes the above by also hiding `WorkerGlobalScope` global in
Node compat mode.
