Fix UB in `as_ptr_cast_mut` documentation
changelog: none
Fixes#10628
There's no `String::as_mut_ptr` surprisingly, so the example is actually calling `str::as_mut_ptr` on an empty `str`
Links to README.md files must actually be links to index.md files,
because of the inner workings of `mdbook`.
Also use the latest mdbook version in CI.
Clear with drain
Fixes#10572: both the original intent of the issue (extending `clear_with_drain`) and the false negative for `collection_is_never_read` I found in the process are fixed by this PR.
changelog: [`clear_with_drain`]: extend to 5 other types of containers. [`collection_is_never_read`]: fix false negative for `String`s.
remove unusued `#![feature(drain_filter)]`
The unstable feature does not appear to be used and its presence blocks work in https://github.com/rust-lang/rust/pull/104455

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.
