Deserialize `Msrv` directly in `Conf`
Gives the error a span pointing to the invalid config value
Also puts `Conf` itself in the `OnceLock` rather than just the `Msrv` for [the `register_late_mod_pass` work](https://github.com/rust-lang/rust/pull/116731) since it will be used from two different callbacks

add lint for struct field names
changelog: [`struct_field_names`]: lint structs with the same pre/postfix in all fields or with fields that are pre/postfixed with the name of the struct.
fixes#2555
I've followed general structure and naming from the code in [enum_variants](b788addfcc/clippy_lints/src/enum_variants.rs) lint, which implements the same logic for enum variants.
Don't emit `needless_pass_by_ref_mut` if the variable is used in an unsafe block or function
Fixes https://github.com/rust-lang/rust-clippy/issues/11586.
Fixes https://github.com/rust-lang/rust-clippy/issues/11180.
As suggested in the two issues above, this lint should not be emitted if this an unsafe function or if the argument is used in an unsafe block.
changelog: [`needless_pass_by_ref_mut`]: Don't emit if the variable is used in an unsafe block or function
side effect for `enum_variants`:
use .first() instead of .get(0) in enum_variants lint
move to_camel_case to str_util module
move module, enum and struct name repetitions check to a single file `item_name_repetitions`
rename enum_variants threshold config option
Add regression test for #11610 about mutable usage of argument in async function for the `needless_pass_by_ref_mut` lint
Fixes https://github.com/rust-lang/rust-clippy/issues/11610.
This was already fixed. I simply added a regression test.

Make `multiple_unsafe_ops_per_block` ignore await desugaring
The await desugaring contains two calls (`Poll::new_unchecked` and `get_context`) inside a single unsafe block. That violates the lint.

[`unnecessary_lazy_eval`]: reduce applicability if closure has return type annotation
Fixes#11672
We already check if closure parameters don't have type annotations and reduce the applicability to `MaybeIncorrect` if they do, since those help type inference and removing them breaks code. We didn't do this for return type annotations however. This PR adds it. This doesn't change it to produce a fix that will compile, but it will prevent rustfix from auto-applying it.
(In general I'm not sure if we can suggest a fix that will compile. In this specific example, it might be possible to suggest `&[] as &[u8]`, but as-casts won't always work, e.g. `Default::default() as &[u8]` is a compile error, so just reducing applicability should be a safe fix in any case for now)

[`get_first`]: lint on non-primitive slices
Fixes#11594
I left the issue open for a couple days before making the PR to see if anyone has something to say, but it looks like there aren't any objections to removing this check that prevented linting on non-primitive slices, so here's the PR now.
There's a couple of instances in clippy itself where we now emit the lint. The actual relevant change is in the first commit and fixing the `.get(0)` instances in clippy itself is in the 2nd commit.

Fix/11134
Fix#11134
Hir of `qpath` will be `TypeRelative(Ty { kind: Path(LangItem...` when a closure contains macro (e.g. https://github.com/rust-lang/rust-clippy/issues/11651) and #11134, it causes panic.
This PR avoids panicking and emitting incomplete path string when `qpath` contains `LangItem`.

`impl_trait_in_params` now supports impls and traits
Before this PR, the lint `impl_trait_in_params`. This PR gives the lint support for functions in impls and traits. (Also, some pretty heavy refactor)

Fix ice in `redundant_locals`
Fixes#11619
Rebinding over macro like the code below, idents will be different (`x#4` and `x#0` in that case).
```rust
fn reassign_in_macro() {
let x = 10;
macro_rules! mac {
($i:ident) => {
let mut x = x;
}
}
mac!(y);
}
```
It causes unwrapping `None`.

Improve `redundant_locals` help message
Fixes#11625
AFAIK, `span_lint_and_help` points the beginning of spans when we pass multiple spans to the second argument, so This PR I also modified its help span and its message.
lint result of the given example in the issue will be:
```console
error: redundant redefinition of a binding `apple`
--> src/main.rs:5:5
|
5 | let apple = apple;
| ^^^^^^^^^^^^^^^^^^
|
help: `apple` is initially defined here
--> src/main.rs:4:9
|
4 | let apple = 42;
| ^^^^^
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#redundant_locals
```
I hope that this change might help reduce user confusion, but I'd appreciate alternative suggestions:)
