Don't allow adjustments for `manual_map`
fixes: #7077
The other option here would be to add the return type to the closure. It would be fine for simple types, but longer types can be rather unwieldy. Could also implement the adjustment manually.
changelog: Don't lint `manual_map` when type adjustments are added. e.g. autoderef
tabs_in_doc_comments: Fix ICE due to char indexing
This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.
More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.
This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output. But I don't think we handle those cases
anywhere in Clippy currently?

Fix FP in `wrong_self_convention` lint
Previously, this lint didn't check into impl block when it was implementing a trait.
Recent improvements (#6924) have moved this check and some impl blocks are now checked but they shouldn't, such as in #7032.

Deprecate `filter_map`
Since #6591, `filter_map` does not even lint `filter().map()`. The cases that are still linted make no sense IMO. So this just removes/deprecates it.

Fix FP in `single_component_path_imports` lint
Fix FP in `single_component_path_imports` lint when the import is reused with `self`, like in `use self::module`.

This is continuation of #6192 after inactivity.

consider mutability on useless_vec suggestions
fixes#7035
changelog: Now the suggested by `useless_vec` considers mutability to suggest either `&[]`, as before, or `&mut []` if the used reference is mutable.

New Lint: `branches_sharing_code`
This lint checks if all `if`-blocks contain some statements that are the same and can be moved out of the blocks to prevent code duplication. Here is an example:
```rust
let _ = if ... {
println!("Start"); // <-- Lint for code duplication
let _a = 99;
println!("End"); // <-- Lint for code duplication
false
} else {
println!("Start");
let _b = 17;
println!("End");
false
};
```
This could be written as:
```rust
println!("Start");
let _ = if ... {
let _a = 99;
false
} else {
let _b = 17;
false
};
println!("End");
```
---
This lint will get masked by the `IF_SAME_THEN_ELSE` lint. I think it makes more sense to only emit one lint per if block. This means that the folloing example:
```rust
if ... {
let _a = 17;
} else {
let _a = 17;
}
```
Will only trigger the `IF_SAME_THEN_ELSE` lint and not the `SHARED_CODE_IN_IF_BLOCKS` lint.
