New lint [`tuple_array_conversions`]
Closes#10748
PS, the implementation is a bit ugly 😅 ~~I will likely refactor soon enough :)~~ Done :D
changelog: New lint [`tuple_array_conversions`]
Also, lint question_mark for `let...else` clauses that can be simplified to use `?`.
This lint isn't perfect as it doesn't support the unstable try blocks.
[significant_drop_tightening] Fix#10413Fix#10413
This is quite a rewrite that unfortunately took a large amount of time. I tried my best to comment what is going on to easy review but feel free to ask any question.
The problem basically is that the current algorithm is only taking into consideration single blocks which means that things like the following don't work or show unpredictable results.
```rust
let mutex = Mutex::new(1);
{
let lock = mutex.lock().unwrap();
{
let _ = *lock;
}
}
```
The solve the issue, each path that refers a lock is now being tracked individually.

New lint [`redundant_at_rest_pattern`]
Closes#11011
It's always a great feeling when a new lint triggers on clippy itself 😄
changelog: New lint [`redundant_at_rest_pattern`]
suggests `is_some_and` over `map().unwrap`
changelog: Enhancement: [`option_map_unwrap_or`] now considers the [`msrv`] config when creating the suggestion.
* modified option_map_unwrap_or lint to recognise when an `Option<T>` is mapped to an `Option<bool>` with false being used when `None` is detected; suggests the use of `is_some_and` instead
* msrv is set to 1.70.0 for this lint; when `is_some_and` was stabilised
fixes#9125
[`question_mark`]: don't lint inside of `try` block
Fixes#8628.
Diff looks a bit noisy because I had to move the two functions into an impl, because they now need to access the structs `try_block_depth` field to see if they're inside a try block.
changelog: [`question_mark`]: don't lint inside of `try` block
[`option_if_let_else`]: suggest `.as_ref()` if scrutinee is of type `&Option<_>`
Fixes#10729
`Option::map_or` takes ownership, so if matching on an `&Option<_>`, we need to suggest `.as_ref()` before calling `map_or` to get the same effect and to not cause a borrowck error.
changelog: [`option_if_let_else`]: suggest `.as_ref()`/`.as_mut()` if scrutinee is of type `&Option<_>`/`&mut Option<_>`
[`unused_async`]: don't lint if function is part of a trait
Fixes#10459.
We shouldn't lint if the function is part of a trait, because the user won't be able to easily remove the `async`, as this will then not match with the function signature in the trait definition

New lints ['`needless_pub_self`], [`pub_with_shorthand`] and [`pub_without_shorthand`]
Closes#10963Closes#10964
changelog: New lints ['`needless_pub_self`], [`pub_with_shorthand`] and [`pub_without_shorthand`]
Use substring matching for TESTNAME
Restores the previous behaviour of matching using a substring match rather than needing a full match
changelog: none
Add `BLESS` for compile-test and some cleanup
changelog: none
Allows passing the environment variable `BLESS` to bless tests, which is useful when you want to bless internal tests - `BLESS= cargo uitest -Finternal`
Also updates a place in the docs referring to `cargo dev bless` and removes some unused test deps
