Since the error kind (`io::ErrorKind::other`) is in the root context,
the error message must be found in the root context as well to compute
the correct span to remove.

It can be error-prone for developers to manually change literals with
mixed uppercase and lowercase letters into consistently all-lowercase or
all-uppercase literals. Therefore, this lint rule should suggest
alternative literals.

Since the error kind (`io::ErrorKind::other`) is in the root context,
the error message must be found in the root context as well to compute

This PR:
- lints more case of raw pointer comparisons
- do not omit the named function to raw pointer conversion before
suggesting
- trigger the `ptr_eq` lint only if `cmp_null` doesn't trigger first, as
this is a more specialized version
- lints against `!=` in addition to `==`
The `ptr_eq` code has been moved from under `operators` to `ptr.rs`, in
order to benefit from factorization.

Clippy gives wrong suggestions when the key is not `Copy`. As suggested
in #9925, in such cases Clippy will simply warn but no fix.

This feature was stabilized, so the FormatArgs lints should check if the MSRV of
the stabilization is met, rather than checking if the feature is enabled.
It is not possible to write a declarative macro, that produces an attribute w/o
an item attached to it. This means that the `check_item` will already insert the
span in the map, if it came from an expansion. So additionally checking if the
macro came from an expansion doesn't add anything here. So the
`check_attribute` function, and with that the problematic `attr.span()` call can
be completely removed.
Fixes#14303
The `looks_like_refdef` function was assuming the range was valid, this
just adds a check to ensure that is the case. It also works around a
subtraction underflow due to the same invalid range.
changelog: [`doc_nested_refdefs`]: Fix#14287 by avoiding invalid ranges
When the manually stripped entity receives a name as the first use
through a simple `let` statement, this name can be used in the generated
`if let Some(…)` expression instead of a placeholder.
Fix#14183
changelog: [`manual_strip`]: reuse existing identifier in suggestion
when possible
These method chains can be expressed concisely with `if`/`else`.
changelog: [`obfuscated_if_else`]: support `then().unwrap_or_else()` and
`then_some().unwrap_or_else()`
```rust
let mut tmp = vec![1, 2, 3];
for b in &mut tmp {
*b = !*b;
}
```
must not suggest the invalid `tmp.fill(!*b)`.
In addition, there is another commit which cleans up two function calls
with no effect.
Fix#14189
changelog: [`manual_slice_fill`]: ensure that the initialization
expression doesn't reference the iterator
