MacOS tends to not distribute evenly, so just don't assert that requests
were served by > 1 worker on mac.
Also added a check that all workers start, so we at least check that on
macos.
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.

This commit adds capability to format HTML, Svelte, Vue, Astro and Angular
files.
"--unstable-html" is required to format HTML files, and "--unstable-component"
flag is needed to format other formats. These can also be specified in the config
file.

This commit adds another test suite that runs all Deno unit tests
with `DENO_FUTURE=1` flag to ensure all APIs are working as
expected, once Deno 2 is released.

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 commit stabilizes HMR functionality and renames
`--unstable-hmr` to `--watch-hmr`. The `--unstable-hmr`
flag is still working, but hidden from the help output.
It will be removed in Deno 2.
Once https://github.com/denoland/deno/pull/24958 lands
we should improve grouping of `--watch` and `--watch-hmr`
flags.
This PR integrates [Malva](https://github.com/g-plane/malva) into `deno

This commit updates permission prompt to add a link
to the documentation for particular flag.
Additionally the box drawings around the prompt have been slightly
altered for better visibility.

This moves YAML formatting behind an unstable flag for Deno 1.46. This
will make it opt-in to start and then we can remove the flag to make it
on by default in version of Deno after that.
This can be specified by doing `deno fmt --unstable-yaml` or by
specifying the following in a deno.json file:
```json
{
"unstable": ["fmt-yaml"]
}
```
This change aims to replace all relative import specifiers targeted at
`tests/util/std` with mapped ones (using a `deno.json` file). Towards
updating the `std` git submodule.
Two small changes:
- In our BYONM errors, suggest running `deno install` instead of `npm
install` if `DENO_FUTURE` is set
- Only emit warning about `deno install` changes if you do `deno install
<foo>` with deno_future unset

Currently, importing Node-Addons modules in a standalone binary results
in a `missing symbol called` error
(https://github.com/denoland/deno/issues/24614). Because the NAPI
symbols are not exported in this mode. This PR should fix the issue.
Originally landed in
f6fd6619e7.
Reverted in https://github.com/denoland/deno/pull/24574.
This reland contains a fix that sends "Accept: */*" header for calls made
from "FileFetcher". Absence of this header made downloading source code
from JSR broken. This is tested by ensuring this header is present in the
test server that servers JSR packages.

This commit re-implements `ext/fetch` and all dependent crates
using `hyper` and `hyper-util`, instead of `reqwest`.
The reasoning is that we want to have greater control and access
to low level `hyper` APIs when implementing `fetch` API as well
as `node:http` module.
