Extend `implicit_saturating_sub` lint
Fixes#10070.
It can serve as base if we want to add equivalent checks for other arithmetic operations.
Also one important note: when writing this lint, I realized that I could check for wrong conditions performed beforehand on subtraction and added another part in the lint. Considering they both rely on the same checks, I kept both in the same place. Not sure if it makes sense though...
changelog: Extend `implicit_saturating_sub` lint
Add new lint: `used_underscore_items`
Closes#13260
---
changelog: new [`used_underscore_items`] lint against using items with a single leading underscore
Add lint for `unused_result_ok`
This PR adds a lint to capture the use of `expr.ok();` when the result is not _really_ used.
This could be interpreted as the result being checked (like it is with `unwrap()` or `expect`) but
it actually only ignores the result.
`let _ = expr;` expresses that intent better.
This was also mentionned in #8994 (although not being the main topic of that issue).
changelog: [`misleading_use_of_ok`]: Add new lint to capture `.ok();` when the result is not _really_ used.

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`]
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.

Fixes#758
