Refactor `disallowed_methods` and narrow span
Using the span of the call site just produces noisy diagnostics for long calls. Especially multi-line calls.

Clarify that `modulo_one` only applies to ints
changelog: [`modulo_one`]: (docs) Clarify that it only applies to integers
This might be nitpicky, but it's more technically correct.
It also helps if a user skims through the docs, because they may believe it also applies to `{float}`s. This doc edit minimizes that possibility
Rename thread_local_initializer_can_be_made_const to missing_const_for_thread_local
Close#12934
As discussed at #12934 name `thread_local_initializer_can_be_made_const` sounds against convention for other lints which describe the issue/wrong code but not suggestion and it is quite long. The new name take example from existing lint `missing_const_for_fn`
changelog: `thread_local_initializer_can_be_made_const` : Rename to [`missing_const_for_thread_local`]

Fixes#11234
changelog: new lint: [`cfg_not_test`]
I don't know whether to lint only the `attr` or also the item associated to it. I guess this would mean putting the check in another place than `check_attribute` but I can't find a way to get the associated item to the attribute.
Also, I'm not sure how to document this lint, I feel like my explications are bad.
Remove `is_in_test_module_or_function`
Uses are replaced with `is_in_test` for consistency with other lints and to simplify the implementation of the lints. This means the module name is no longer checked, but that was a horrible hack from a time when late passes couldn't see `#[cfg(..)]` attributes.

[`unnecessary_to_owned`]: catch `to_owned` on byte slice to create temporary `&str`
Closes#11648
Detects the pattern `&String::from_utf8(bytes.to_vec()).unwrap()` and suggests `core::str::from_utf8(bytes).unwrap()`, which avoids the unnecessary intermediate allocation.
I decided to put this in the existing `unnecessary_to_owned` lint (rather than creating a new lint) for a few reasons:
- we get to use some of its logic (for example, recognizing any of the functions in the `to_owned` family, e.g. `to_vec`)
- the actual inefficient operation that can be avoided here is the call to `.to_vec()`, so this is in a way similar to the other cases caught by `unnecessary_to_owned`, just through a bunch of type conversions
- we can make this more "generic" later and catch other cases, so imo it's best not to tie this lint specifically to the `String` type

[`missing_const_for_fn`]: fix suggestions for fn with abi that requires `const_extern_fn` feature
closes: #13008
---
changelog: [`missing_const_for_fn`]: fix suggestions for fn with abi that requires `const_extern_fn` feature.
This patch adds a new lint that checks for potentially harder to read
byte char slices: `&[b'a', b'b']` and suggests to replace them with the
easier to read `b"ab"` form.

Add new lint `hashset_insert_after_contains`
This PR closes https://github.com/rust-lang/rust-clippy/issues/11103.
This is my first PR creating a new lint (and the second attempt of creating this PR, the first one I was not able to continue because of personal reasons). Thanks for the patience :)
The idea of the lint is to find insert in hashmanps inside if staments that are checking if the hashmap contains the same value that is being inserted. This is not necessary since you could simply call the insert and check for the bool returned if you still need the if statement.

rustdoc: update to pulldown-cmark 0.11
r? rustdoc
This pull request updates rustdoc to the latest version of pulldown-cmark. Along with adding new markdown extensions (which this PR doesn't enable), the new pulldown-cmark version also fixes a large number of bugs. Because all text files successfully parse as markdown, these bugfixes change the output, which can break people's existing docs.
A crater run, https://github.com/rust-lang/rust/pull/121659, has already been run for this change.
The first commit upgrades and fixes rustdoc. The second commit adds a lint for the footnote and block quote parser changes, which break the largest numbers of docs in the Crater run. The strikethrough change was mitigated in pulldown-cmark itself.
