Scope `missing_docs_in_private_items` to only private items
`missing_docs_in_private_items` currently detects missing docs for public items as well as private. Since `missing_docs`already covers public items, this PR updates `missing_docs_in_private_items` to only cover private items.
Fixes#1895
changelog: [`missing_docs_in_private_items`]: Apply lint only to private items (used to be public and private)
Run dogfood to completion
Run dogfood on all packages before failing the test. Failing early is painful on lints which trigger on multiple crates.

Add configuration to lint missing docs of `pub(crate)` items
Fixes this: https://github.com/rust-lang/rust-clippy/issues/5736#issuecomment-1412442404
TODO:
- [x] Needs docs
- [x] Needs better names
- [x] Should `pub` items be checked to when this new option is enabled? I'm saying no because `missing_docs` already exists
`@flip1995` I'd like to get some input from you :)

changelog: Enhancement: [`missing_docs_in_private_items`]: Added new configuration `missing-docs-in-crate-items` to lint on items visible within the current crate. For example, `pub(crate)` items.

Within a larger expression, when the type of `Box::new(T::default())` is

proposed replacement `Box::<T>::default()`.
[significant_drop_tightening] Ignore inexpensive statements
Not all statements that follow the last use of a lock guard are expensive and can therefore be ignored by the lint.
```rust
pub fn foo() -> i32 {
let mutex = Mutex::new(1);
let lock = mutex.lock().unwrap();
let rslt = *lock;
let another = rslt;
another
}
```

manual_let_else: do not suggest semantically different replacements
The problem is that this lint does not consider the possibility that the divergent branch can come first and that the patterns may overlap. This led to incorrect suggestions, previously registered as correct in the tests themselves:
```rust
let v = match build_enum() {
_ => continue,
Variant::Bar(v) | Variant::Baz(v) => v,
};
```
had a `let Variant::Bar(v) | Variant::Baz(v) = v else { continue; }` suggestion, which is obviously wrong as the original code `continue`s in any case. Issue #10241 gives another example.
The code now checks that the divergent branch comes second. It could be extended later (I've added a TODO) to check for non-overlapping patterns.
Fixes#10241.
changelog: [`manual_let_else`] do not suggest non equivalent replacements in `match`
Stop bytes_nth from suggesting code that does not compile
Fixes#10151
As discussed in the issue, this PR changes the lint in 2 ways
1. Replace `bytes().nth(n).unwrap()` with `as_bytes()[n]`
2. Replace other `bytes().nth(n)` with `as_bytes().get(n).copied()`

Stop doc_markdown requiring backticks on links to external websites
Fixes#10302
This lint currently checks that any link should be enclosed with `backticks` if the title looks like a lang item. This PR changes the lint to only run on internal links. External links, indicated by `http` or `https`, are skipped.
This PR also reorganises `pulldown_cmark` imports to bypass the clippy lint enforcing 100 line functions.

Add question-mark-used lint
This lint complains when the question mark operator (try operator) is used. This is a restriction lint that can be useful on local scopes where a custom error handling macro is supposed to be used to augment the error based on local scope data before returning.

Add `let_underscore_untyped`
Fixes#6842
This adds a new pedantic `let_underscore_untyped` lint which checks for `let _ = <expr>`, and suggests to either provide a type annotation, or to remove the `let` keyword. That way the author is forced to specify the type they intended to ignore, and thus get forced to re-visit the decision should the type of `<expr>` change. Alternatively, they can drop the `let` keyword to truly just ignore the value no matter what.

Fix false positives for `extra_unused_type_parameters`
Don't lint external macros. Also, if the function body is empty, any type parameters with bounds on them are not linted. Note that only the body needs be empty - this rule still applies if the function takes any arguments.

r? `@matthiaskrgr`
It is not sufficient to ignore break from a block inside the loop.
Instructions after the break must be ignored, as they are unreachable.
This is also true for all instructions in outer blocks and loops
until the right block is reached.
This lint complains when the question mark operator (try operator)
is used. This is a restriction lint that can be useful on local
scopes where a custom error handling macro is supposed to be used
to augment the error based on local scope data before returning.
