return_and_then: only lint returning expressions (#14783)
If an expression is not going to return from the current function of
closure, it should not get linted.

This also allows `return` expression to be linted, in addition to the
final expression. Those require blockification and proper indentation.

Fix clippy::version of elidable_lifetime_names to 1.87 (#14654)
relates to rust-lang/rust-clippy#14653

changelog: [`elidable_lifetime_names`]: Fix clippy version that this
lint was introduced in.

It might be good to have some automation to check that the version is
correct.
IIUC the version should be the current nightly version at the time a PR
is merged.
If a release happens while a PR is open, the version needs to be bumped
- this is easy to forget.

Add new confusing_method_to_numeric_cast lint (#13979)
Fixes https://github.com/rust-lang/rust-clippy/issues/13973.

I don't think we can make `fn_to_numeric_cast_any` to be emitted in some
special cases. Its category cannot be changed at runtime.

I think in this case, the best might be a specialized new lint so we can
target exactly what we want.

Fix unnecessary_unwrap emitted twice in closure (#14763) (#14770)
The problem is that `check_fn` is triggered by both function and
closure, and `visit_expr` can visit expressions in another closures
within a function or closure.

So just skip walking in a inner closure.

changelog: Fix [`unnecessary_unwrap`] emitted twice in closure which
inside in a function or another closure.

4cbd116460 unwrap.rs: internal naming cleanup
Since its conception, the lint has been extended from `Option`
only to `Option` and `Result`, but some function names and comment still
references only `Option`.

Also, one cascaded `if` was replaced by a shorter `match`.

add allow_unused config to missing_docs_in_private_items for underscored
field

changelog: [`missing_docs_in_private_items`]: add allow_unused config to
missing_docs_in_private_items for underscored field

Explaination (quoted from the issue's author): When writing structures
that must adhere to a specific format (such as memory mapped I/O
structures) there are inevitably fields that are "reserved" by
specifications and thus need no documentation. In cases where private
docs are preferred but reserved fields need no explanation, having to
#[allow/expect] this lint removes the ability to check for otherwise
used fields' documentation.

Replace str path utils with new PathLookup type (#14705)
The `&[&str]` path based `clippy_utils` have been removed and replace
with a new type `PathLookup`:

-
[`match_trait_method`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.match_trait_method.html)
-
[`match_qpath`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.match_qpath.html)
-
[`match_path`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.match_path.html)
-
[`match_any_def_paths`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.match_any_def_paths.html)
-
[`match_def_path`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.match_def_path.html)
-
[`match_type`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/ty/fn.match_type.html)
-
[`get_trait_def_id`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.get_trait_def_id.html)

Internally `PathLookup` is a lazy call to `lookup_path` (the new name
for
[`def_path_res`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.def_path_res.html)
to distinguish it from
[`path_res`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.path_res.html))

The `invalid_paths` internal lint is removed, it could be reimplemented
but it feels redundant since every path should be covered by a test
anyway

### User facing changes

- `manual_saturating_arithmetic` now checks for `u32::MAX/MIN` instead
of only detecting the legacy numeric consts (`std::u32::MAX/MIN`),
`clippy::legacy_numeric_constants` will redirect usages of the legacy
versions to the new one

- `allow-invalid = true` now suppresses all invalid path warnings,
currently you can run into a warning that can't be ignored in some
situations, e.g. with `serde` without the `derive` feature

  ```
  warning: expected a macro, found a trait
   --> /home/gh-Alexendoo/temp/clippy.toml:2:5
    |
  2 |     { path = "serde::Serialize", allow-invalid = true },
    |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  ```

- Re-exports of primitives types like `std::primitive::*` no longer work
in `disallowed-types`, this seems acceptable since it would be unusual
to deny a primitive this way rather than writing e.g. `usize`. Type
aliases such as `c_char` are unaffected

- A similar slight performance improvement to
https://github.com/rust-lang/rust-clippy/pull/14650
