Add `max_line_length` to `.editorconfig`, matching `rustfmt.toml`
Add `max_line_length` to `.editorconfig` to match the `max_width` in `rustfmt.toml`.

Make elaboration generic over input
Combines all the `elaborate_*` family of functions into just one, which is an iterator over the same type that you pass in (e.g. elaborating `Predicate` gives `Predicate`s, elaborating `Obligation`s gives `Obligation`s, etc.)
Clippy Book Chapter Updates Reborn: Type Checking
This PR adds a new chapter to the book: "Type Checking", it hasn't changed a lot from the source mainly because there wasn't many reviews on it and I haven't see a lot of things that needed a change.
## Notes
- I have some doubts about the whole "`is_*` Usage" section, what do you think about it.
- For discussion about the whole project, please use the tracking issue for the project #10597 (It also contains a timeline, discussions, and more information)
changelog: Add a new "Type Checking" chapter to the book

(Small) Fix broken links for Rust merge
rust-lang/rust#110003's CI is [currently broken](https://github.com/rust-lang/rust/actions/runs/4628510374/jobs/8187672234?pr=110003) because of broken links. This PR fixes that.
It was tested against `lintcheck` and found another broken link in `usage.md` (apart from CI's broken links)
changelog:Fix broken links in the book
Sorry for putting more work on you, but you're the one doing the Rust PR

new lint: suspicious_doc_comments
Fixes#10485.
This PR adds a new lint (`suspicious_doc_comments`) that triggers when the user writes `///!` or `/**!`.
This is almost certainly a mistake and the user probably meant to write an inner doc comment (`//!`, `/*!`) to document the module or crate that this comment is contained in.
changelog: [`suspicious_doc_comments`]: new lint
fix `single_component_path_imports` FP on `self::<import>::..`
fixes#10549
I noticed that a couple functions in the file I was working on took `cx` as a parameter but didn't use them, so I removed that. Can revert if desired because it isn't related to my changes.
changelog: [`single_component_path_imports`] don't suggest removing import when it is used as `self::<import>::..`

Make redundant_async_block a more complete late pass
This lets us detect more complex situations: `async { x.await }` is simplified into `x` if:
- `x` is an expression without side-effect
- or `x` is an `async` block itself
In both cases, no part of the `async` expression can be part of a macro expansion.
Fixes#10509.
Fixes#10525.
changelog: [`redundant_async_block`] Do not lint expressions with side effects.
This lets us detect more complex situations: `async { x.await }` is
simplified into `x` if:
- `x` is an expression without side-effect
- or `x` is an async block itself
In both cases, no part of the `async` expression can be part of a macro
expansion.
Add `tests_outside_test_module` lint
Adds `tests_outside_test_module` from #10506. This PR **doesn't** close the issue, just resolves task 1.
changelog: [`tests_outside_test_module`]: The lint has been added
Fix bug with getting parent directories in `lookup_conf_file`
Currently `lookup_conf_file` doesn't canonicalize the configuration directory before using [`PathBuf::pop`](https://doc.rust-lang.org/std/path/struct.PathBuf.html#method.pop) to get the parent directory. This isn't usually an issue when clippy is invoked via `cargo clippy` as `CARGO_MANIFEST_DIR` is already canonicalized. However, this currently causes `clippy-driver` to ignore any `clippy.toml` in any parent directories when `CARGO_MANIFEST_DIR` and `CLIPPY_CONF_DIR` are not set.
changelog: Fix a bug that would cause parent directories not to be searched for `clippy.toml` when using `clippy-driver` directly.
Mini-fix `double_must_use` for async functions
From Rust 1.67 onwards, the `#[must_use]` attribute also applies to the `Future::Output` (rust-lang/rust#100633). So the lint `double_must_use` was linting all async functions. This PR changes the `double_must_use` lint so it ignores `async` functions.
