Remove `multispan_sugg[_with_applicability]`
They're thin wrappers over the corresponding diag method so we should just use that instead

Add test for `try_err` lint within try blocks.
Fixes#5757
Turns out the current `try_err` implementation already skips expressions inside of a try block.
When inside of a try block, `Err(_)?` is desugared to a `break` instead of normal `return` . This makes `find_return_type()` function at [this line](eb4d88e690/clippy_lints/src/matches/try_err.rs (L29)) always returns `None` and skips the check.
I just added a test case for try block.

Fix [`redundant_slicing`] when the slice is behind a mutable reference
Fixes#12751
changelog: Fix [`redundant_slicing`] when the slice is behind a mutable reference and a immutable reference is expected.
When a suggestion part is for already present code, do not highlight it. If after that there are no highlights left, do not show the suggestion at all.
Fix clippy lint suggestion incorrectly treated as `span_help`.
Fix `redundant_closure` false positive with closures has return type contains `'static`
Fix#13073 .
Please enable "ignore white-space change" settings in github UI for easy reviewing.
HACK: The third commit contains a hack to check if a type `T: 'static` when `fn() -> U where U: 'static`.
I don't have a clean way to check for it.

Add possibility to focus on search input using keyboard
This PR adds the possibility to focus on the search input with `S` or `/` like in rustdoc and `mdbook` and `docs.rs` (unification++). Pressing escape will blur it.

Emit `if_let_mutex` in presence of other mutexes
Currently (master, not nightly nor stable) `if_let_mutex` does not emit a warning here:
```rs
let m1 = Mutex::new(10);
let m2 = Mutex::new(());
if let 100..=200 = *m1.lock().unwrap() {
m2.lock();
} else {
m1.lock();
}
```
It currently looks for the first call to `.lock()` on *any* mutex receiver inside of the if/else body, and only later (outside of the visitor) checks that the receiver matches the mutex in the scrutinee. That means that in cases like the above, it finds the `m2.lock()` expression, stops the visitor, fails the check that it's the same mutex (`m2` != `m1`) and then does not look for any other `.lock()` calls.
So, just make the receiver check also part of the visitor so that we only stop the visitor when we also find the right receiver.
The first commit has the actual changes described here. The sceond one just unnests all the `if let`s
