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.
`napi_call_function` should use our equiv of NAPI_PREAMBLE (`&mut Env`
instead of `*mut Env`) since it needs to set error codes based on
whether the body of the function raised a JS exception.

Fixes #26085.
Adds a basic retry utility with some defaults, starts off with a 100ms
wait, then 250ms, then 500ms
I've applied the retry in the http client, reusing an existing function,
so this also applies to retrying downloads of deno binaries in `upgrade`
and `compile`. I can make a separate function that doesn't retry so this
doesn't affect `upgrade` and `compile`, but it seemed desirable to have
retries there too, so I left it in.
This came up on Discord as a question so I thought it's worth adding a
hint for this as it might be a common pitfall.

Originally I wanted to put them in package.json if there's no deno.json,
but on second thought it makes more sense to just create a deno.json

The significant delay was caused by Nagel's algorithm + delayed ACKs in
Linux kernels. Here's the [kernel

This change removes the handling of `--check` and `--no-check` flags from
`deno repl` subcommand.
Currently these flags don't have effects, and the help output for these
options are incorrect and confusing.
closes #26042
This commit fixes the issue of import name conflict in case the named
export and default export have the same name by letting named export
take precedence over default export.
Fixes #26009
When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
