This is a rewrite of the `Deno.serve` API to live on top of hyper
1.0-rc3. The code should be more maintainable long-term, and avoids some
of the slower mpsc patterns that made the older code less efficient than
it could have been.
Missing features:
- `upgradeHttp` and `upgradeHttpRaw` (`upgradeWebSocket` is available,
however).
- Automatic compression is unavailable on responses.
Fixes https://github.com/denoland/deno/issues/18700
Timeline of the events that lead to the bug.
1. WebSocket handshake complete
2. Server on `read_frame` holding an AsyncRefCell borrow of the
WebSocket stream.
3. Client sends a TXT frame after a some time
4. Server recieves the frame and goes back to `read_frame`.
5. After some time, Server starts a `write_frame` but `read_frame` is
still holding a borrow!
^--- Locked. read_frame needs to complete so we can resume the write.
This commit changes all writes to directly borrow the
`fastwebsocket::WebSocket` resource under the assumption that it won't
affect ongoing reads.
This should produce a little less garbage and using an object here
wasn't really required.

This commit adds a new core API `opAsync2` to call an async op with
atmost 2 arguments. Spread argument iterators has a pretty big perf hit
when calling ops.

Use u16 to represent the kind of event (0 - 6) & event code > 6 is
treated as the close code. This way we can represent all events + the
close code in a single JS number. This is safe because (as per RFC 6455)
close code from 0-999 are reserved & not used.

Follow-up to #18210:
* we are passing the generated `cfg` object into the state function
rather than passing individual config fields
* reduce cloning dramatically by making the state_fn `FnOnce`
* `take` for `ExtensionBuilder` to avoid more unnecessary copies
* renamed `config` to `options`
This implements two macros to simplify extension registration and centralize a lot of the boilerplate as a base for future improvements:
* `deno_core::ops!` registers a block of `#[op]`s, optionally with type
parameters, useful for places where we share lists of ops
* `deno_core::extension!` is used to register an extension, and creates
two methods that can be used at runtime/snapshot generation time:
`init_ops` and `init_ops_and_esm`.

This commit splits "<ext_name>::init" functions into "init_ops" and
"init_ops_and_esm". That way we don't have to construct list of
ESM sources on each startup if we're running with a snapshot.
In a follow up commit "deno_core" will be changed to not have a split
between "extensions" and "extensions_with_js" - it will be embedders'
responsibility to pass appropriately configured extensions.
Prerequisite for https://github.com/denoland/deno/pull/18080
This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the
modules loaded from this loader to "ext:".
"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.
Closes https://github.com/denoland/deno/issues/18020
There's no point for this API to expect result. If something fails it should
result in a panic during build time to signal to embedder that setup is
wrong.

Tugstenite already sends a pong for a recieved ping. This automatically
happens when the socket read is being driven. From
https://github.com/snapview/tokio-tungstenite/issues/88
> You need to read from the read-side of the socket so that it
receives/handles pings, and on the next write it would then send the
corresponding pong.
Here's the source:
e1033afd95/src/protocol/mod.rs (L374-L380)
```rust
// Upon receipt of a Ping frame, an endpoint MUST send a Pong frame in
// response, unless it already received a Close frame. It SHOULD
// respond with Pong frame as soon as is practical. (RFC 6455)
if let Some(pong) = self.pong.take() {
trace!("Sending pong reply");
self.send_one_frame(stream, pong)?;
}
```
WIth this patch, all Autobahn tests from 1-8 pass. Fixed cases: 2.1,
2.2, 2.3, 2.4, 2.6, 2.9, 2.10, 2.11, 5.6, 5.7, 5.8, 5.19, 5.20

This PR refactors all internal js files (except core) to be written as
ES modules.
`__bootstrap`has been mostly replaced with static imports in form in
`internal:[path to file from repo root]`.
To specify if files are ESM, an `esm` method has been added to
`Extension`, similar to the `js` method.
A new ModuleLoader called `InternalModuleLoader` has been added to
enable the loading of internal specifiers, which is used in all
situations except when a snapshot is only loaded, and not a new one is
created from it.

Welcome to better optimised op calls! Currently opSync is called with parameters of every type and count. This most definitely makes the call megamorphic. Additionally, it seems that spread params leads to V8 not being able to optimise the calls quite as well (apparently Fast Calls cannot be used with spread params).
Monomorphising op calls should lead to some improved performance. Now that unwrapping of sync ops results is done on Rust side, this is pretty simple:
```
opSync("op_foo", param1, param2);
// -> turns to
ops.op_foo(param1, param2);
```
This means sync op calls are now just directly calling the native binding function. When V8 Fast API Calls are enabled, this will enable those to be called on the optimised path.
Monomorphising async ops likely requires using callbacks and is left as an exercise to the reader.
