Change error about unknown attributes to a warning

Hard errors should go through a future-compatibility phase first, especially since these attributes only have no effect and don't actively cause bugs.

Follow-up to https://github.com/rust-lang/rust/pull/82662. Fixes ecosystem breakage like https://github.com/rust-lang/rust-clippy/issues/6832.

This prevents breakage across the ecosystem, since the error was just
introduced recently without first having a warning period.

Rollup merge of #81223 - GuillaumeGomez:generate-redirect-map, r=jyn514
[rustdoc] Generate redirect map file

Fixes #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"
}
```

Rollup merge of #82516 - PoignardAzur:inherent-impl-ty, r=oli-obk
Add incomplete feature gate for inherent associate types.

Mentored by ``````@oli-obk``````

So far the only change is that instead of giving an automatic error, the following code compiles:

```rust
struct Foo;

impl Foo {
    type Bar = isize;
}
```

The backend work to make it actually usable isn't there yet. In particular, this:

```rust
let x : Foo::Bar;
```

will give you:

```sh
error[E0223]: ambiguous associated type
  --> /$RUSTC_DIR/src/test/ui/assoc-inherent.rs:15:13

Rollup merge of #82655 - SkiFire13:fix-issue-81314, r=estebank
Highlight identifier span instead of whole pattern span in `unused` lint

Fixes #81314

This pretty much just changes the span highlighted in the lint from `pat_sp` to `ident.span`. There's however an exception, which is in patterns with shorthands like `Point { y, ref mut x }`, where a suggestion to change just `x` would be invalid; in those cases I had to keep the pattern span. Another option would be suggesting something like `Point { y, x: ref mut _x }`.

I also added a new test since there weren't any test that checked the `unused` lint with optional patterns.

Rollup merge of #82018 - jyn514:no-dummy-cache, r=camelid,GuillaumeGomez
Remove the dummy cache in `DocContext`; delete RenderInfo

The same information is available everywhere; the only reason the dummy
cache was needed is because it was previously stored in three different
places. This consolidates the info a bit so the cache in `DocContext` is
used throughout. As a bonus, it also completely removes `RenderInfo`.

- Return a `Cache` from `run_global_ctxt`, not `RenderInfo`
- Remove the unused `render_info` from `run_renderer`
- Remove RenderInfo altogether

Helps with https://github.com/rust-lang/rust/pull/82014. The next step is to move the `populate()` call before the `collect_intra_doc_links` pass, which currently breaks because a) lots of the cache is populated in early passes, and b) intra_doc_links itself sets some info with `register_res`. I'm working on separate PR for that to avoid making too many big changes at once.

Rollup merge of #81932 - jyn514:rustdoc-logging, r=Mark-Simulacrum
Always compile rustdoc with debug logging enabled when `download-rustc` is set

Previously, logging at DEBUG or below would always be silenced, because
rustc compiles tracing with the `static_max_level_info` feature. That
makes sense for release artifacts, but not for developing rustdoc.

Instead, this compiles two different versions of tracing: one in the
release artifacts, distributed in the sysroot, and a new version
compiled by rustdoc. Since `rustc_driver` is always linked to the
version of sysroot, this copy/pastes `init_env_logging` into rustdoc.

To avoid compiling an unnecessary version of tracing when
`download-rustc` isn't set, this adds a new `using-ci-artifacts`
feature for rustdoc and passes that feature in bootstrap.

Addresses https://github.com/rust-lang/rust/issues/81930. This builds on https://github.com/rust-lang/rust/pull/79540.

Fixes an issue where `unaligned_references` is not triggered in external macros, unlike `safe_packed_borrows`.
Also, given that this lint is planned to eventually change to hard error (#82525), it would make sense for this lint to be triggered for external macros as well.

be069a687a Remove krate.version; fix crate_version in JSON
Previously, `JsonRenderer::after_krate` called `krate.version.clone()`.
The problem was it did that after the version was already moved into the
cache, so it would always be None. The fix was to get the version from
the cache instead.

6dc9934641 Remove deleted pass from rustdoc test suite
`src/test/rustdoc-ui/deprecated-attrs.rs`
tells rustdoc to run the `collapse-docs` pass, which no longer exists
(it was removed in https://github.com/rust-lang/rust/pull/80261).
Rustdoc doesn't actually give a proper diagnostic here; instead it
prints an `error!` log. Now that tracing is compiled unconditionally,
the log is now being emitted by default, because it's at the error
level.

rustdoc shouldn't be using `error!` logging for diagnostics in the first
place, but in the meantime this change gets the testsuite to pass.

Rollup merge of #81856 - Smittyvb:utf16-warn, r=matthewjasper
Suggest character encoding is incorrect when encountering random null bytes

This adds a note whenever null bytes are seen at the start of a token unexpectedly, since those tend to come from UTF-16 encoded files without a [BOM](https://en.wikipedia.org/wiki/Byte_order_mark) (if a UTF-16 BOM appears it won't be valid UTF-8, but if there is no BOM it be both valid UTF-16 and valid but garbled UTF-8). This approach was suggested in https://github.com/rust-lang/rust/issues/73979#issuecomment-653976451.

Closes #73979.

992b914b6b Recover from X<Y,Z> when parsing const expr
This adds recovery when in array type syntax user writes

    [X; Y<Z, ...>]

instead of

    [X; Y::<Z, ...>]

Fixes #82566

Note that whenever we parse an expression and know that the next token
cannot be `,`, we should be calling
check_mistyped_turbofish_with_multiple_type_params for this recovery.
Previously we only did this for statement parsing (e.g. `let x = f<a,
b>;`). We now also do it when parsing the length field in array type
syntax.

fb631a55c2 Fix turbofish recovery with multiple generic args
check_mistyped_turbofish_with_multiple_type_params was previously
expecting type arguments between angle brackets, which is not right, as
we can also see const expressions. We now use generic argument parser
instead of type parser.

Test with one, two, and three generic arguments added to check
consistentcy between

1. check_no_chained_comparison: Called after parsing a nested binop
   application like `x < A > ...` where angle brackets are interpreted as
   binary operators and `A` is an expression.

2. check_mistyped_turbofish_with_multiple_type_params: called by
   `parse_full_stmt` when we expect to see a semicolon after parsing an
   expression but don't see it.

   (In `T2<1, 2>::C;`, the expression is `T2 < 1`)
