6124: Better normalized crate name usage r=jonas-schievink a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/5343
Closes https://github.com/rust-analyzer/rust-analyzer/issues/5932
Uses normalized name for code snippets (to be able to test the fix), hover messages and documentation rewrite links (are there any tests for those?).
Also renamed the field to better resemble the semantics.

5846: Add references to fn args during completion r=matklad a=adamrk
When completing a function call, if there is an argument taken as a ref or mut ref which matches the name and type of a variable in scope, we will insert a `&` or `&mut` when filling in the function arguments. This addresses https://github.com/rust-analyzer/rust-analyzer/issues/5449.
E.g.
```rust
fn foo(x: &i32) {}
fn main() {
let x = 5;
foo # completing foo here generates `foo(&x)` now instead of `foo(x)`
}
```

It handles fn-like macros too, and will handle attribute macros in the
future

5971: Implement async blocks r=flodiebold a=oxalica
Fix #4018
@flodiebold already gave a generic guide in the issue. Here's some concern about implementation detail:
- Chalk doesn't support generator type yet.
- Adding generator type as a brand new type (ctor) can be complex and need to *re-introduced* builtin impls. (Like how we implement closures before native closure support of chalk, which is already removed in #5401 )
- The output type of async block should be known after type inference of the whole body.
- We cannot directly get the type from source like return-positon-impl-trait. But we still need to provide trait bounds when chalk asking for `opaque_ty_data`.
- During the inference, the output type of async block can be temporary unknown and participate the later inference.
`let a = async { None }; let _: i32 = a.await.unwrap();`
So in this PR, the type of async blocks is inferred as an opaque type parameterized by the `Future::Output` type it should be, like what we do with closure type.
And it really works now.
Well, I still have some questions:
- The bounds `AsyncBlockImplType<T>: Future<Output = T>` is currently generated in `opaque_ty_data`. I'm not sure if we should put this code here.
- Type of async block is now rendered as `impl Future<Output = OutputType>`. Do we need to special display to hint that it's a async block? Note that closure type has its special format, instead of `impl Fn(..) -> ..` or function type.

`hir` should know nothing about URLs, markdown and html. It should
only be able to:
* resolve stringy path from documentation
* generate canonical stringy path for a def
In contrast, link rewriting should not care about semantics of paths
and names resolution, and should be concern only with text mangling
bits.

Doc comments *are* attributes, so there's no reason to have two crates
here.

We generally shouldn't expose TypeRef out of hir. So, let's just use a
placehoder here.

5643: Add new consuming modifier, apply consuming and mutable to methods r=matklad a=Nashenas88
This adds a new `consuming` semantic modifier for syntax highlighters.
This also emits `mutable` and `consuming` in two cases:
- When a method takes `&mut self`, then it now has `function.mutable` emitted.
- When a method takes `self`, and the type of `Self` is not `Copy`, then `function.consuming` is emitted.

The options are Shared, Mutable, Consuming, and Copied. Use this to add proper
highlighting to methods based on usage.

Conjecture: it's impossible to use hir::Path *correctly* from an IDE.
I am not entirely sure about this, and we might need to add it back at
some point, but I have to arguments that convince me that we probably
won't:
* `hir::Path` has to know about hygiene, which an IDE can't set up
properly.
* `hir::Path` lacks identity, but you actually have to know identity
to resolve it correctly
