This is a reproduction and fix for a very obscure bug where the Deno
runtime locks up we end up polling an empty JoinSet and attempt to
resolve ops after-the-fact. There's a small footgun in the JoinSet API
where polling it while empty returns Ready(None), which means that it
never holds on to the waker. This means that if we aren't testing for
this particular return value and don't stash the waker ourselves for a
future async op to eventually queue, we can end up losing the waker
entirely and the op wakes up, notifies tokio, which notifies the
JoinSet, which then has nobody to notify đą.

returns (#19642)
Fixes the WPT tests that test w/invalid codes. Also explicitly ignoring
some h2 tests to hopefully prevent flakes.
The previous changes to WebSocketStream introduced a bug where the close
errors were not made available if the `pull` method was re-entrant.

This is a fix for issue #19644, concerning the `parseCssColor` function
in the file `ext/console/01_console.js`. Changes made on lines
2756-2758. To sum it up:
> The internal `parseCssColor` function currently parses 3/4-digit hex
colors incorrectly. For example, it parses the string `#FFFFFF` as
`[255, 255, 255]` (as expected), but returns `[240, 240, 240]` for
`#FFF`, when it should return the same triplet as the former.
While it's not going to cause a fatal runtime error, it did bug me
enough to fix it real quick.

Attempts to fix the thread_safe_callback flakiness. It's unclear what
the flake is about, the exit code is apparently `C0000005` or
`ACCESS_VIOLATION`, pointing to an issue with memory access. My only
guess is that maybe dropping the `Option<extern "C" fn ()>` is somehow
checking the validity of the function pointer and since the function has
been dropped, the pointer is no longer valid and sometimes points to
memory that should not be accessed.
So now the will explicitly drop the functions before they get
deallocated. If this doesn't fix the flake then something beyond my
understanding is wrong.

This is also a performance improvement because declaration file hashes
don't need to be stored in the lockfile.

The copyright checker was allowing files with code above the copyright
line in a few places, mainly as a result of IDEs ordering imports
improperly.
This makes the check more robust, and adds a whitelist of valid lines
that may appear before the copyright line.

(#19611)
âŠnclusion" (#19519)"
This reverts commit 28a4f3d0f5383695b1d49ccdc8b0f799a715b2c2.
This change causes failures when used outside Deno repo:

If you can reliably reproduce this panic, include the
reproduction steps and re-run with the RUST_BACKTRACE=1 env
var set and include the backtrace in your report.

The following code:
```rust
use deno_core::op;
#[op]
fn ops_serde_v8(value: serde_v8::Value) {
//
}
fn main() {
//
}
```
...with the following `Cargo.toml`:
```toml
[package]
name = "playground"
version = "0.1.0"
edition = "2021"
[dependencies]
deno_core = "0.191.0"
serde_v8 = "0.102.0"
```
...will not compile with the error:
```
error[E0433]: failed to resolve: use of undeclared crate or module `v8`
--> src/main.rs:3:1

3 | #[op]
| ^^^^^ use of undeclared crate or module `v8`
|
= note: this error originates in the attribute macro `op` (in Nightly builds, run with -Z macro-backtrace for more info)
```
This PR is fixing the above issue by properly quoting
`deno_core::v8::Value` instead of `v8::Value`.

Implements `Result` in fast-calls. Note that the approach here is
slightly different. Rather than store the last result in the `OpState`,
we put it into the `OpCtx` which saves us a lookup and lock in the error
case. We do not have to lock this field as it's guaranteed only one
runtime and thread can ever access it.
The fastcall path for many ops can avoid doing a great deal of work,
even for `Result` return values. In the previous iteration of `ops`, all
`Result`-returning functions would fetch and lock the `OpState`,
regardless of whether it was used or not.

This test is very flaky.

Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.

This is a new op system that will eventually replace `#[op]`.
Features
- More maintainable, generally less-coupled code
- More modern Rust proc-macro libraries
- Enforces correct `fast` labelling for fast ops, allowing for visual
scanning of fast ops
- Explicit marking of `#[string]`, `#[serde]` and `#[smi]` parameters.
This first version of op2 supports integer and Option<integer>
parameters only, and allows us to start working on converting ops and
adding features.

Fixes #19568
Values are not coerced to the desired type during deserialisation. This
makes serde_v8 stricter.

This fixes a bug in file metadata parsing logic, which now properly
evaluates boolean fields when forwarding for atime / mtime / birthtime
values.

`ZeroCopyBuf` was convenient to use, but sometimes it did hide details
that some copies were necessary in certain cases. Also it made it way to easy
for the caller to pass around and convert into different values. This commit
splits `ZeroCopyBuf` into `JsBuffer` (an array buffer coming from V8) and
`ToJsBuffer` (a Rust buffer that will be converted into a V8 array buffer).
As a result some magical conversions were removed (they were never used)
limiting the API surface and preparing for changes in #19534.

Fixes a bug I noticed when deriving a key based from `ECDH`. Similar
issue is also mentioned in #14693, where they derive a key using
`PBKDF2`
- In the WebCrypto API, `deriveKey()` is equivalent to `deriveBits()`
followed by `importKey()`
- But, `deriveKey()` requires just `deriveKey` in the `usages` of the
`baseKey` parameter. The `deriveBits` usage is not required to be
allowed. This is the uniform behaviour in Node, Chrome and Firefox.
- The impl currently has userland-accessible `SubtleCrypto.deriveKey()`
and `SubtleCrypto.deriveBits()`, as well as an internal `deriveBits()`
(this is the one that accesses the ffi).
- Also, `SubtleCrypto.deriveKey()` checks if `deriveKey` is an allowed
usage and `SubtleCrypto.deriveBits()` checks if `deriveBits` is an
allowed usage, as required.
- However, the impl currently calls the userland accessible
`SubtleCrypto.deriveBits()` in `SubtleCrypto.deriveKey()`, leading to an
error being thrown if the `deriveBits` usage isn't present.
- Fixed this by making it call the internal `deriveBits()`
instead.
