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`.

Fix `vec-box-size-threshold` off-by-one error
The docs for `vec-box-size-threshold` say "The size of the boxed type in bytes, where boxing in a `Vec` is allowed", but previously a boxed type of exactly that size wasn't allowed in `Vec`.
changelog: [`vec_box`]: Fix off-by-one error for `vec-box-size-threshold` configuration.
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.
CC #8574
changelog: [`or_fun_call`]: Mention false-positives, move to nursery.
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 :)

Fix is_async_fn to check FnKind::Method
This is a follow-up PR of https://github.com/rust-lang/rust-clippy/pull/9828 to support also async methods.

Make `bool_to_int_with_if` a pedantic lint
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

changelog: Fix two `needless_borrow` false positives, one involving borrows in `if`-`else`s, the other involving qualified function calls
