[`collapsible_match`] specify field name when destructuring structs
changelog: [`collapsible_match`] specify field name when destructuring structs
fix https://github.com/rust-lang/rust-clippy/issues/9647
I wasn't the sure about the best way to convey the message in the lint message since it does not use suggestion. Because I liked the former output highlighting both spans, I've left it as before, only modifying the span label.
Fix bug introduced by #9386#9386 introduced a potential out-of-bounds array access. Specifically, a location returned by `local_assignments` could have [`location.statement_index` equal to `mir.basic_blocks[location.block].statements.len()`](b8a9a507bf/clippy_utils/src/mir/mod.rs (L129)), in which case the location would refer to the block terminator:
b8a9a507bf/clippy_lints/src/dereference.rs (L1204-L1206)
I suspect the bug is not triggerable now, because of checks leading up to where it occurs. But a future code change could make it triggerable. Hence, it should be fixed.

Add `unused_format_specs` lint
Currently catches two cases:
An empty precision specifier:
```rust
// the same as {}
println!("{:.}", x);
```
And using formatting specs on `format_args!()`:
```rust
// prints `x.`, not `x .`
println("{:5}.", format_args!("x"));
```

Add new lint `partial_pub_fields`

Resolve#9604
Expand internal lint `unnecessary_def_path`
This PR does essentially two things:
* Separates the internal lints into modules by pass. (`internal_lints.rs` was over 1400 lines, which is a little unruly IMHO.)
* ~Adds a new~ Expands the `unnecessary_def_path` internal lint to flag hardcoded paths to diagnostic and language items.
My understanding is that the latter is currently done by reviewers. Automating this process should make things easier for both reviewers and contributors.
I could make the first bullet a separate PR, or remove it entirely, if desired.

fix `box-default` linting `no_std` non-boxes
This fixes#9653 by doing the check against the `Box` type correctly even if `Box` isn't there, as in `no_std` code. Thanks to `@lukas-code` for opening the issue and supplying a reproducer!

Adds a machine applicable suggestion to convert the `Into` impl into a `From` one to `from_over_into`
Also adds a note explaining that `impl From<Local> for Foreign` is fine if the `Into` type is foreign

Fix edition revision ui tests
#9605 had me wondering how the edition revision tests were working for `manual_assert` but not for `@nyurik,` but it turns out `manual_assert`'s tests weren't working either. I checked how `rust-lang/rust` does it and apparently it comes down to whitespace, `//[rev] edition:X` works 😬
Removes the revisions from `match_wild_err_arm` as I couldn't find any edition dependant behaviour there

add tests in `implicit_saturating_sub` lint
This adds more tests to the `implicit_saturating_sub` lint to rule out certain false positives that have appeared in the past.
Now with those false positives out of the equation, we can move the lint to `style`.

Change uninlined_format_args into a style lint
As [previously discussed](https://github.com/rust-lang/rust-clippy/pull/9233#issuecomment-1256361205), the `uninlined_format_args` should probably be a part of the default style because `println!("{}", foo)` is not as concise or easy to understand as `println!("{foo}")`
changelog: [`uninlined_format_args`]: change to be the default `style`

```
print!("error: something failed at {}", (Location::caller().to_string()));
