Return multiple resolutions from `def_path_res`
Changes `def_path_res` to return all the resolutions matching the path rather than the first one (with a namespace hint that covered some cases). This would fix any issues that come up with multiple versions of the same crate being present as they all have the same crate name
It also adds resolution of `impl _ {}` items for local items, and removes struct field resolution as it didn't seem to be used anywhere
I tested it on a local crate and it worked for the multiple crate issue, but I couldn't come up with a test that worked well with `// aux-build`, maybe `// aux-crate` after https://github.com/rust-lang/rust/pull/103266 could work but I'm not sure on that either

Extend `needless_borrowed_reference` to structs and tuples, ignore _
changelog: [`needless_borrowed_reference`]: Lint struct and tuple patterns, and patterns containing `_`
Now lints patterns like
```rust
&(ref a, ref b)
&Tuple(ref a, ref b)
&Struct { ref a, ref b }
&(ref a, _)
```

`never_loop`: don't emit AlwaysBreaks if it targets a block
ref: https://github.com/rust-lang/rust-clippy/pull/9837#issuecomment-1312788194
The previous fix (#9837) was too simple and ignored all break commands inside a labelled block, regardless of whether their destination was a labelled block or a loop. This fix tracks all the labelled blocks in scope to ensure that only breaks targeting loops are considered.
changelog: [`never_loop`]: prevent false negatives from `breaks` nested in labelled blocks
When we run `cargo test` in `clippy_lints` directory, it will generate
`foo.txt` in the directory.
In order to avoid that, add `no_run` to rustdoc which contains
`File::create`.
Introduced an ignored_ids parameter.
Takes O(n^2) time in the worst case.
Can be changed to collect block ids in first phase,
and then filter with binary search in second.
feat: lint unchecked subtraction of a 'Duration' from an 'Instant'
Hello all, I tried to tackle the open issue #9371 and this is what I came up with.
I have a difficulty currently - some tests are failing:
```
failures:
[ui] ui/manual_instant_elapsed.rs
```
The `manual_instant_elapsed` is failing because of `Instant::now() - duration` test, this now gets also picked by `unchecked_duration_subtraction` lint.
What is the correct way to proceed in this case? Simply update the `.stderr` file for `manual_instant_elapsed` lint?
changelog: [`unchecked_duration_subtraction`]: Add lint for unchecked subtraction of a `Duration` from an `Instant`.
fixes#9371
Make it clear that `or_fun_call` can be a false-positive
Also move it to nursery so that the false-positives can be dealt with.

Add `unnecessary_safety_doc` lint
changelog: [`unnecessary_safety_doc`]: Add `unnecessary_safety_doc` lint
fixes https://github.com/rust-lang/rust-clippy/issues/6880
This lint does not trigger for private functions, just like `missing_safety_docs`. Reason for that was implementation simplicity and because I figured asking first would make more sense, so if it should trigger for private functions as well let me know and I'll fix that up as well.
[`fn_params_excessive_bools`] Make it possible to allow the lint at the method level
changelog: FP: [`fn_params_excessive_bools`]: `#[allow]` now works on methods
fix https://github.com/rust-lang/rust-clippy/issues/9687
Tested without committing but `#[allow]`ing now works. Also rewrote the lint to be a late lint while at it :)
r? `@xFrednet`
In all the cases I've observed, it did not make the code clearer. Using
bools as integer is frowned upon in some languages, in others it's
simply not possible.
You can find comments on the original pull request #8131 that agree with
this point of view.

Address issues 9739 and 9782
This PR fixes#9739 in the manner I suggested in https://github.com/rust-lang/rust-clippy/issues/9739#issuecomment-1296802376.
This PR also fixes the compilation failures in #9782 (but doesn't address `@e00E's` other objections).
Fixes#9739
r? `@Jarcho`
changelog: Fix two `needless_borrow` false positives, one involving borrows in `if`-`else`s, the other involving qualified function calls
