This commit also adds `tracing` to NotificationDispatcher/RequestDispatcher,
bumps `rust-analyzer-salsa` to 0.17.0-pre.6, `always-assert` to 0.2, and
removes the homegrown `hprof` implementation in favor of a vendored
tracing-span-tree.

This PR is the result of running `cargo clippy --fix && cargo fmt` in the root of the repository. I did not manually review all the changes, but just skimmed through a few of them. The tests still pass, so it seems fine.
Add a new config to allow renaming of non-local defs
With #15656 we started disallowing renaming of non-local items. Although this makes sense there are some false positives that impacted users' workflows. So this config aims to mitigate this by giving users the liberty to disable this feature.
The reason why this is a draft is that I saw one of the tests fail and I am not sure if the "got" result even syntactically makes sense
Test case is :
```rust
check(
"Baz",
r#"
//- /lib.rs crate:lib new_source_root:library
pub struct S;
//- /main.rs crate:main deps:lib new_source_root:local
use lib::S$0;
"#,
"use lib::Baz;"
);
```
```
Left:
use lib::Baz;
Right:
use lib::Baz;Baz
Diff:
use lib::Baz;Baz
```

internal: Follow rustfmt's algorithm for ordering imports when ordering and merging use trees
Updates use tree ordering and merging utilities to follow rustfmt's algorithm for ordering imports.
The [rustfmt implementation](6356fca675/src/imports.rs) was used as reference.
fix: Acknowledge `pub(crate)` imports in import suggestions
rust-analyzer has logic that discounts suggesting `use`s for private imports, but that logic is unnecessarily strict - for instance given this code:
```rust
mod foo {
pub struct Foo;
}
pub(crate) use self::foo::*;
mod bar {
fn main() {
Foo$0;
}
}
```
... RA will suggest to add `use crate::foo::Foo;`, which not only makes the code overly verbose (especially in larger code bases), but also is disjoint with what rustc itself suggests.
This commit adjusts the logic, so that `pub(crate)` imports are taken into account when generating the suggestions; considering rustc's behavior, I think this change doesn't warrant any extra configuration flag.
Note that this is my first commit to RA, so I guess the approach taken here might be suboptimal - certainly feels somewhat hacky, maybe there's some better way of finding out the optimal import path 😅

Resolve panic in `generate_delegate_methods`
Fixes#16276
This PR addresses two issues:
1. When using `PathTransform`, it searches for the node corresponding to the `path` in the `source_scope` during `make::fn_`. Therefore, we need to perform the transform before `make::fn_` (similar to the problem in issue #15804). Otherwise, even though the tokens are the same, their offsets (i.e., `span`) differ, resulting in the error "Can't find CONST_ARG@xxx."
2. As mentioned in the first point, `PathTransform` searches for the node corresponding to the `path` in the `source_scope`. Thus, when transforming paths, we should update nodes from right to left (i.e., use **reverse of preorder** (right -> left -> root) instead of **postorder** (left -> right -> root)). Reasons are as follows:
In the red-green tree (rowan), we do not store absolute ranges but instead store the length of each node and dynamically calculate offsets (spans). Therefore, when modifying the left-side node (such as nodes are inserted or deleted), it causes all right-side nodes' spans to change. This, in turn, leads to PathTransform being unable to find nodes with the same paths (due to different spans), resulting in errors.
fix: Fix `ast::Path::segments` implementation
calling `ast::Path::segments` on a qualifier currently returns all the segments of the top path instead of just the segments of the qualifier.
The issue can be summarized by the simple failing test below:
```rust
#[test]
fn path_segments() {
//use ra_ap_syntax::ast;
let path: ast::Path = ...; // e.g. `ast::Path` for "foo::bar::item".
let path_segments: Vec<_> = path.segments().collect();
let qualifier_segments: Vec<_> = path.qualifier().unwrap().segments().collect();
assert_eq!(path_segments.len(), qualifier_segments.len() + 1); // Fails because `LHS = RHS`.
}
```
This PR:
- Fixes the implementation of `ast::Path::segments`
- Fixes `ast::Path::segments` callers that either implicitly relied on behavior of previous implementation or exhibited other "wrong" behavior directly related to the result of `ast::Path::segments` (all callers have been reviewed, only one required modification)
- Removes unnecessary (and now unused) `ast::Path::segments` alternatives
SymbolInformation::kind is finer-grained than the SCIP symbol suffix.
This also fixes a bug where all type aliases where treated like type
parameters.
```
trait SomeTrait {
type AssociatedType; // ← this is SomeTrait#[AssociatedType]
}
type MyTypeAlias = u8; // ← this used to be [MyTypeAlias]
// and now is MyTypeAlias#
```
To build the SymbolInformation::signature_documentation we need access
to the “label” when building the TokenStaticData, preferably without
any markdown markup.
Therefore this refactors ide::hover::render::definition and its helper
functions to give easier access to the label alone.
For local variables, this gets the moniker from the enclosing
definition and stores it into the TokenStaticData.
Then it builds the scip symbol for that moniker when building the
SymbolInformation.
