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.
[`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`
Update lint example for `collapsible_str_replace`
To fix this warning:
```
warning: the borrowed expression implements the required traits

16 | let hello = "hesuo worpd".replace(&['s', 'u', 'p'], "l");
| ^^^^^^^^^^^^^^^^ help: change this to: `['s', 'u', 'p']`

Changelog for Rust 1.65
Roses are red,
violets are blue,
another 6 weeks,
another changelog, yahoo!
This did not rhyme,
luckily, not a crime.
I want to say something smart,
but I am out of time.

Improve `needless_lifetimes`
This PR makes the following improvements to `needless_lifetimes`.
* It fixes the following false negative, where `foo` is flagged but `bar` is not:
```rust
fn foo<'a>(x: &'a u8, y: &'_ u8) {}
fn bar<'a>(x: &'a u8, y: &'_ u8, z: &'_ u8) {}
```
* It flags more cases, generally. Previously, `needless_borrow` required *all* lifetimes to be used only once. With the changes, individual lifetimes are flagged for being used only once, even if not all lifetimes are.
* Finally, it tries to produce more clear error messages.
changelog: fix `needless_lifetimes` false negative involving functions with multiple unnamed lifetimes
changelog: in `needless_lifetimes`, flag individual lifetimes used only once, rather than require all lifetimes to be used only once
changelog: in `needless_lifetimes`, emit "replace with `'_`" warnings only when applicable, and point to a generic argument
fix: support `map_or` for `or_fun_call` lint
fixes https://github.com/rust-lang/rust-clippy/issues/8993
The methods defined in `KNOW_TYPES`, except for `map_or`, accepts only one argument, so the matching `if let [arg] = args` works only for these methods.
This PR adds `rest_arg` argument to `check_general_case` method and handling of cases with two arguments to support `map_or`.
changelog: `or_fun_call` support `map_or`
* add `rest_arg` to pass second argument from `map_or(U, F)`
* extract some procedures into closure
* add `rest_arg` to pass second argument from `map_or(U, F)`
* extract some procedures into closure
refac: rename rest_arg/second_arg
refac: organize function argument order
* put `second_arg` next to `arg` argument
* Check for `const`s and `static`s from external crates
* Check for `LangItem`s
* Handle inherent functions which have the same name as a field
* Also check the following functions:
* `match_trait_method`
* `match_def_path`
* `is_expr_path_def_path`
* `is_qpath_def_path`
* Handle checking for a constructor to a diagnostic item or `LangItem`
use `is_integer_literal` more
I noticed that we have the `is_integer_literal` function in our `clippy_utils`, yet almost everywhere people still match int literal expressions manually. So I searched for instances to replace and shorten the code a bit.

fix a ui test
use `into`
fix clippy ui test
fix a run-make-fulldeps test
implement `IntoQueryParam<DefId>` for `OwnerId`
use `OwnerId` for more queries
change the type of `ParentOwnerIterator::Item` to `(OwnerId, OwnerNode)`
Fixes#9504
Compiler generated call `into_iter` nodes return empty substs
which we need when checking it's predicates. Handle this by
simply exitting when we encounter one. This change introduces
false negatives in place of the ICEs.
