Skip inner ordering checking in presence of #[repr(…)] (#14610)
A representation attribute `#[repr(…)]` might indicate that the ordering
of the fields or the variants is dictated by the API the code is
interfacing with. Better not lint with `arbitrary_source_item_ordering`
in this case.

changelog: [`arbitrary_source_item_ordering`]: do not lint inside items
with `#[repr]` attribute

match_same_arms, ifs_same_cond: lint once per same arm/condition (#14637)
A large fraction of the lints emitted in CI lintcheck come from [this
`match`](https://github.com/unicode-rs/unicode-normalization/blob/v0.1.23/src/tables.rs#L34289),
currently for `n` same arms `((n - 1) * n)/2` lints are emitted, with
this change it will be emitted as a single lint

clippy_dev refactor (#14616)
Based on rust-lang/rust-clippy#13223

Various refactoring on `clippy_dev` before upgrading rename and
splitting `clippy_lints` into multiple crates.

Some improvements:
* The working directory is set to the root clippy directory. Running
from a subdirectory was kind of supported before sometimes. Now it just
works.
* File won't be written unless they're actually updated. Most of the
time they weren't written, but a few cases slipped through.
* Buffers are reused more for the negligible speed boost.

Post non_std_lazy_statics type warnings onto the right node (#14740)
When a `non_std_lazy_statics` warning is generated about an item type
which can be replaced by a standard library one, ensure that the lint
happens on the item HIR node so that it can be expected.

changelog: [`non_std_lazy_statics`]: generate the warning onto the right
node

Fixes rust-lang/rust-clippy#14729

Note that this doesn't change anything on lints generated for the
`lazy_static::lazy_static` macro because the `expect` attribute cannot
be applied to a macro.

Add internal lint derive_deserialize_allowing_unknown (#14360)
Adds an internal lint to check for `#[derive(serde::Deserialize)]`
without
[`#[serde(deny_unknown_fields)]`](https://serde.rs/container-attrs.html#deny_unknown_fields).

Today, if you run Clippy with the following clippy.toml, Clippy will
produce a warning, but there will be no accompanying note:
```toml
# In the following configuration, "recommendation" should be "reason" or "replacement".
disallowed-macros = [
    { path = "std::panic", recommendation = "return a `std::result::Result::Error` instead" },
]
```
```sh
$ cargo clippy
    Checking a v0.1.0 (/home/smoelius/tmp/a)
warning: use of a disallowed macro `std::panic`
 --> src/lib.rs:2:5
  |
2 |     panic!();
  |     ^^^^^^^^
  |
  = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#disallowed_macros
  = note: `#[warn(clippy::disallowed_macros)]` on by default
```
The underlying problem is: the enum that derives `serde::Deserialize`
([`DisallowedPathEnum`](81643e297c/clippy_config/src/types.rs (L47)))
does not have the attribute `#[serde(deny_unknown_fields)]`.

This lint identifies such problems by checking trait `impl`s. An
alternative I considered was to walk `clippy_config::conf::Conf`
directly. However, that would not catch the `DisallowedPathEnum` case
because it [is not used in `Conf`
directly](81643e297c/clippy_config/src/types.rs (L31)).

Just to be clear, no one asked for this. So I hope the maintainers do
not mind.

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.
