It doesn't exist on Windows, so we bring our own unified diff implementation.

Fixes rust-lang#82409

The rustdoc team does not currently use the `I-nominated` label, unlike
the libs and compiler teams (and maybe others). One reason for this is
that the other teams discuss their nominated issues in meetings, while
rustdoc is an async-only team.

However, it might be helpful to start using the `I-nominated` label for
rustdoc. The team currently uses a `cc @rust-lang/rustdoc` ping as the
equivalent, but it's easier to track issues when they use `I-nominated`.
Also we'd be more consistent with the other teams' procedures.

Since rustdoc doesn't have meetings, I propose we instead use the
triagebot notify Zulip functionality to create a topic in `#rustdoc` on
Zulip and ping the team. So it would look a bit like the procedure for
WG-prioritization when an issue acquires the `I-prioritize` label.

`redox` and `vxworks` are part of target_family `unix`, thus `cfg(unix)` already implies `cfg(target_os="redox")` and `(target_os="vxworks")`

[rustdoc] Generate redirect map file

Fixes rust-lang#81134.

So with this code:

```rust
#![crate_name = "foo"]

pub use private::Quz;
pub use hidden::Bar;

mod private {
    pub struct Quz;
}

#[doc(hidden)]
pub mod hidden {
    pub struct Bar;
}

#[macro_export]
macro_rules! foo {
() => {}
}
```

It generates:

```json
{
  "foo/macro.foo!.html": "foo/macro.foo.html",
  "foo/private/struct.Quz.html": "foo/struct.Quz.html",
  "foo/hidden/struct.Bar.html": "foo/struct.Bar.html"
}
```

meta: Notify Zulip for rustdoc nominated issues

The rustdoc team does not currently use the `I-nominated` label, unlike
the libs and compiler teams (and maybe others). One reason for this is
that the other teams discuss their nominated issues in meetings, while
rustdoc is an async-only team.

However, it might be helpful to start using the `I-nominated` label for
rustdoc. The team currently uses a `cc ``@rust-lang/rustdoc``` ping as the
equivalent, but it's easier to track issues when they use `I-nominated`.
Also we'd be more consistent with the other teams' procedures.

Since rustdoc doesn't have meetings, I propose we instead use the
triagebot notify Zulip functionality to create a topic in `#rustdoc` on
