This closes #5902.
I only check that the next token isn't equal to `T![:]`, instead of the next two not being equal to `T![::]`. Is that ok?

6350: Make IncorrectDiagnostic match rustc by copying rustc's code. r=popzxc a=ArifRoktim

This closes #6343 and closes #6345.

The old algorithm which used a `DetectedCase` enum, didn't match how rustc thinks of cases. Some inputs can be interpreted as more than 1 case depending on the situation. For example, to rustc:
- `ABCD`: Can be both camel case and upper snake case
- `X86_64`: Can be both camel case and upper snake case

I could've made `detect_case` return a collection of `DetectedCase` and then modified the other code as such, but I think using the same code rustc uses is simpler and a surefire way to achieve the same diagnostics as rustc.

6331: correct hover text for items with doc attribute with raw strings r=matklad a=JoshMcguigan

Fixes #6300 by improving the handling of raw string literals in attribute style doc comments.

This still has a bug where it could consume too many `"` at the start or end of the comment text, just as the original code had. Not sure if we want to fix that as part of this PR or not? If so, I think I'd prefer to add a unit test for either the `as_simple_key_value` function (I'm not exactly sure where this would belong / how to set this up) or create a `fn(&SmolStr) -> &SmolStr` to unit test by factoring out the `trim` operations from `as_simple_key_value`. Thoughts on this? 

6342: Shorter dependency chain r=matklad a=popzxc

Continuing implementing suggestions from the `Completion refactoring` zulip thread.

This PR does the following:

- Removes dependency of `completions` on `assists` by moving required functionality into `ide_db`.
- Moves completely `call_info` crate into `ide_db` as it looks like it fits perfect there.
- Adds a bunch of new tests and docs.
- Adds the re-export of `base_db` to the `ide_db` and removes direct dependency on `base_db` from other crates.

The last point is controversial, I guess, but I noticed that in places where `ide_db` is used, `base_db` is also *always* used. Thus I think the dependency on the `base_db` is implied by the fact of `ide_db` interfaces, and thus it makes sense to just provide `base_db` out of the box.

6251: Semantic Highlight: Add Callable modifier for variables r=matklad a=GrayJack

This PR added the `HighlightModifier::Callable` variant and assigned it to variables and parameters that are fn pointers, closures and implements FnOnce trait.

This allows to colorize these variables/parameters when used in call expression.



6310: Rewrite algo::diff to support insertion and deletion r=matklad a=Veykril

This in turn also makes `algo::diff` generate finer diffs(maybe even minimal diffs?) as insertions and deletions aren't always represented as as replacements of parent nodes now.

6320: Textmate grammar: prevent line comments from breaking block comments (closes #6281) r=matklad a=dustypomerleau

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/6281.

Previously, line comments were able to break block comments by essentially commenting out the closing `*/`, resulting in a never-ending comment. This PR splits block comments into a separate repository group to fix this problem.

Since the comment scopes also include ignored parameters and inferred types, I've added the change proposed by @bnjjj in https://github.com/rust-analyzer/rust-analyzer/pull/6317, in order to close https://github.com/rust-analyzer/rust-analyzer/issues/6311 as well.

6172: Add qualify path assist r=matklad a=Veykril

This implements a `qualify_path` assist which works quite similar to the `auto_import` assist but instead of adding imports to the file it well, qualifies the path. This PR also moves out the `AutoImportAssets` struct and functions from `auto_import` into a utils submodule as most of this is now shared between `auto_import` and `qualify_path`.

Changes made to `AutoImportAssets` are solely in its `search_for_imports` function which now takes a prefixed parameter to discern between using `find_use_path_prefixed` and `find_use_path` as the former is the required behavior by `auto_import` and the latter by this assist.

For missing imported traits instead of importing this will qualify the path with a trait cast as in:
```rust
test_mod::TestStruct::TEST_CONST<|>
```
becomes
```rust
<test_mod::TestStruct as test_mod::TestTrait>::TEST_CONST
```

and for trait methods ideally it would do the following:
```rust
let test_struct = test_mod::TestStruct {};
test_struct.test_meth<|>od()
```
becomes
```rust
let test_struct = test_mod::TestStruct {};
test_mod::TestTrait::test_method(&test_struct)
```

Fixes #4124.

Declaration names sounds like a name of declaration -- something you

we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).

7a21e9302e Add a hacky remidy for #6038
The proper fix I think is:

* move rust-lang/rust library crates to a separate workspace
* when packaging rust-src component, vendor sources of external deps

6246: Follow symlinks when walking project trees r=lnicola a=dfoxfranke

Fixes #3691.

~~WIP pending further testing~~:

- [X] Verify that symlinked files get indexed.
- [x] Verify that files in symlinked directories get indexed.
- [x] Verify that inotify events are properly received and handled when the target of a symlink resides outside the project tree.

6220: implement binary operator overloading type inference r=flodiebold a=ruabmbua

Extend type inference of *binary operator expression*, by adding support for operator overloads.

Before this merge request, the type inference of binary expressions could only resolve operations done on built-in primitive types. This merge requests adds a code path, which is executed in case the built-in inference could not get any results. It resolves the proper operator overload trait in *core::ops* via lang items, and then resolves the associated *Output* type.

```rust
struct V2([f32; 2]);

#[lang = "add"]
pub trait Add<Rhs = Self> {
    /// The resulting type after applying the `+` operator.
    type Output;

    /// Performs the `+` operation.
    #[must_use]
    fn add(self, rhs: Rhs) -> Self::Output;
}

impl Add<V2> for V2 {
    type Output = V2;

    fn add(self, rhs: V2) -> V2 {
        let x = self.0[0] + rhs.0[0];
        let y = self.0[1] + rhs.0[1];
        V2([x, y])
    }
}

fn test() {
    let va = V2([0.0, 1.0]);
    let vb = V2([0.0, 1.0]);

    let r = va + vb; // This infers to V2 now
}
```

There is a problem with operator overloads, which do not explicitly set the *Rhs* type parameter in the respective impl block. 

**Example:**

```rust
impl Add for V2 {
    type Output = V2;

    fn add(self, rhs: V2) -> V2 {
        let x = self.0[0] + rhs.0[0];
        let y = self.0[1] + rhs.0[1];
        V2([x, y])
    }
}
```

In this case, the trait solver does not realize, that the *Rhs* type parameter is actually self in the context of the impl block. This stops type inference in its tracks, and it can not resolve the associated *Output* type.

I guess we can still merge this back, because it increases the amount of resolved types, and does not regress anything (in the tests).

6207: Extract ImportAssets out of auto_import r=matklad a=Veykril

See https://github.com/rust-analyzer/rust-analyzer/pull/6172#issuecomment-707182140

I couldn't fully pull out `AssistContext` as `find_node_at_offset_with_descend`: 81fa00c5b5/crates/assists/src/assist_context.rs (L90-L92) requires the `SourceFile` which is private in it and I don't think making it public just for this is the right call?
