This patch fixes stdin read hanging on user input when switching tty
mode on Windows
Fixes #21111
On Windows, when switching from line to raw mode:
- Cancel ongoing console read by writing a return keypress to its input
buffer. This blocks the main thread until any ongoing read has been
cancelled to prevent interference with the screen state.
- On the read thread, restore the cursor position to where it was before
writing the enter, undoing its effect on the screen state.
- Restart reading and notify the main thread.
This commit changes `gzip` compression in `Deno.serve` API to flush data
after each write. There's a slight performance regression, but provided
test shows a scenario that was not possible before.

We didn't honour the `position` options of `fd.read` and `fd.write`
because we checked if the buffer is of type `Buffer` instead of just
`Uint8Array`. Node does the latter. In doing so I noticed that the file
handle id was written to a public property which it definitely shouldn't
be. This was probably a typo.

We didn't support the `throwIfNoEntry` option for Node's `fs.lstatSync`
method. Note that the async variant doesn't have this option.

The mixed `number | bigint` representation was useful optimization for
pointers. Now, pointers are represented as V8 externals. As part of the
FFI stabilization effort we want to make `bigint` the only
representation for `u64` and `i64`.
BigInt representation performance is almost on par with mixed
representation with the added benefit that its less confusing and users
don't need manual checks and conversions for doing operations on the
value.

Closes #19697. This fixes a bug where the writeFile API can create
partially-overwritten files which may lead to invalid / corrupt files or
data leakage. It also aligns the behavior of writing a ReadableStream
and writing a Uint8Array to the disk.
`createAsyncFromSyncIterator(x)` which is used in
`ReadableStream.from()` expects `x` as `Iterable` but, previous
implements specify `Iterator` or `IterableIterator`. If it was
`IterableIterator`, it would work, but if it was `Iterator`, an
exception will occur.
Tests have been merged into WPT.

Node sets the default HTTP response status code to 200 on the
`ServerResponse`. We initialised it as `undefined` before which caused a
problem with 11ty's dev server.
Thanks to @vrugtehagel for reporting this issue and finding the correct
fix as well 🎉

The flag lets us exit from read loop without throwing an error when
the stream is cancelled.

If `@@asyncIterator` is `null` or `undefined`, it should ignores and
fallback to `@@iterator`.

The proposal of `ReadableStream.from` uses TC39 [GetIterator][] and
[GetMethod][] within it.
GetMethod treats null as undefined.
So if `@@asyncIterator` is `null` it should be ignored and fallback to
`@@iterator`.
[GetIterator]: https://tc39.es/ecma262/#sec-getiterator
[GetMethod]: https://tc39.es/ecma262/#sec-getmethod

ReadableStream.from({ [Symbol.asyncIterator]: null, [Symbol.iterator]: () => ({ next: () => ({ done: true }) }) }).pipeTo(new WritableStream())

Because the buffers are `MaybeUninit<V8Slice<u8>`, and the owner of the
`BoundedBufferChannel` is not obligated to read each and every bit of
data, we may find that some buffers were not automatically dropped if
unread by the time the `BoundedBufferChannelInner` is dropped.
Possible repro:
```
Deno.serve(() => new Response(new ReadableStream({ start(controller) { controller.enqueue(new Uint8Array(100_000_000)) } })));
```
```bash
while true; do curl localhost:8000 | dd count=1; done
```
This stubs `findSourceMap` in `node:module` by always returning
`undefined` as if it never found a source map. This unblocks the `ava`
test runner.

Some npm libraries like `signal-exit` rely on the length of the listener
array returned by `process.listeners("SIGNT")` to be correct to
function. We weren't tracking `SIG*` events there, which broke those npm
libraries.

Popular test runners like Jest instantiate a new `Process` object
themselves and expect the class constructor to be callable without the
`new` keyword. This PR refactors our `Process` class implementation from
a proper ES2015 class to an ES5-style class which can be invoked both
with and without the `new` keyword like in Node.
Fixes https://github.com/denoland/deno/issues/23863
gRPC depends only on the END_STREAM flag to emit "trailers" event which
is responsible to propagate the errors correctly. This patch uses
Body::is_end_stream() to determine if a stream will end and set the
END_STREAM flag.

Precursor to #23236
This implements the SNI features, but uses private symbols to avoid
exposing the functionality at this time. Note that to properly test this
feature, we need to add a way for `connectTls` to specify a hostname.
This is something that should be pushed into that API at a later time as
well.
```ts
Deno.test(
{ permissions: { net: true, read: true } },
async function listenResolver() {
let sniRequests = [];
const listener = Deno.listenTls({
hostname: "localhost",
port: 0,
[resolverSymbol]: (sni: string) => {
sniRequests.push(sni);
return {
cert,
key,
};
},
});
{
const conn = await Deno.connectTls({
hostname: "localhost",
[serverNameSymbol]: "server-1",
port: listener.addr.port,
});
const [_handshake, serverConn] = await Promise.all([
conn.handshake(),
listener.accept(),
]);
conn.close();
serverConn.close();
}
{
const conn = await Deno.connectTls({
hostname: "localhost",
[serverNameSymbol]: "server-2",
port: listener.addr.port,
});
const [_handshake, serverConn] = await Promise.all([
conn.handshake(),
listener.accept(),
]);
conn.close();
serverConn.close();
}
assertEquals(sniRequests, ["server-1", "server-2"]);
listener.close();
},
);

1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.
