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.
feat: "Normalize import" assist and utilities for normalizing use trees
- Add import/use tree normalization utilities
- Add "normalize import" assist
- Update "merge imports" assist to always apply to the covering use item except for nested use tree selections
- Update "merge imports" assist to avoid adding unnecessary braces when merging nested use tree selections
See [this discussion](https://github.com/rust-lang/rust-analyzer/pull/16372#discussion_r1457244321) for the motivation for the new "normalize import" assist and changes to the "merge imports" assist.
feat: Support for GOTO def from *inside* files included with include! macro
close#14937
Try to implement goto def from *inside* files included with include! macro.
This implementation has two limitations:
1. Only **one** file which calls include! will be tracked. (I think multiple file be included is a rare case and we may let it go for now)
2. Mapping token from included file to macro call file (semantics.rs:646~658) works fine but I am not sure is this the correct way to implement.
`unescape_literal` becomes `unescape_unicode`, and `unescape_c_string`
becomes `unescape_mixed`. Because rfc3349 will mean that C string
literals will no longer be the only mixed utf8 literals.
- Rename it as `MixedUnit`, because it will soon be used in more than
just C string literals.
- Change the `Byte` variant to `HighByte` and use it only for
`\x80`..`\xff` cases. This fixes the old inexactness where ASCII chars
could be encoded with either `Byte` or `Char`.
- Add useful comments.
- Remove `is_ascii`, in favour of `u8::is_ascii`.
fix panic with reference in macro
it panic at `builder.make_mut(segment)`, where segment is from macro expand. And the usage reference in orginal macro call isn't a `PathSegment` so we can't update it in `apply_references`, I can't find a way to deal with it properly so here just filter out the reference in macro. LMK if there are better way to fix this

Expand lint tables && make clippy happy 🎉
This PR expands the lint tables on `./Cargo.toml` and thereby makes `cargo clippy` exit successfully! 🎉Fixes#15918
## How?
In the beginning there are some warnings for rustc.
Next, and most importantly, there is the clippy lint table. There are a few sections in there.
First there are the lint groups.
Second there are all lints which are permanently allowed with the reasoning why they are allowed.
Third there is a huge list of temporarily allowed lints. They should be removed in the mid-term, but incur a substantial amount of work, therefore they are allowed for now and can be worked on bit by bit.
Fourth there are all lints which should warn.
Additionally there are a few allow statements in the code for lints which should be permanently allowed in this specific place, but not in the whole code base.
## Follow up work
- [ ] Run clippy in CI
- [ ] Remove tidy test (at least `@Veykril` wrote this in #15017)
- [ ] Work on temporarily allowed lints
internal: Record FnAbi
This unfortunately breaks our lub coercions, so will need to look into fixing that first, though I am not sure what is going wrong where...
Stubbed some stuff out for the time being.
`cargo clippy --fix`
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
```
The first one succeeds because the functionality is already implemented.
The second one fails and represents the functionality to be implemented
in this PR.
Detect `NulInCStr` error earlier.
By making it an `EscapeError` instead of a `LitError`. This makes it like the other errors produced when checking string literals contents, e.g. for invalid escape sequences or bare CR chars.
NOTE: this means these errors are issued earlier, before expansion, which changes behaviour. It will be possible to move the check back to the later point if desired. If that happens, it's likely that all the string literal contents checks will be delayed together.
One nice thing about this: the old approach had some code in `report_lit_error` to calculate the span of the nul char from a range. This code used a hardwired `+2` to account for the `c"` at the start of a C string literal, but this should have changed to a `+3` for raw C string literals to account for the `cr"`, which meant that the caret in `cr"` nul error messages was one short of where it should have been. The new approach doesn't need any of this and avoids the off-by-one error.

fix: better handling of SelfParam in assist 'inline_call'
fix#15470.
The current `inline_call` directly translates `&self` into `let ref this = ...;` and `&mut self` into `let ref mut this = ...;`. However, it does not handle some complex scenarios.
This PR addresses the following transformations (assuming the receiving object is `obj`):
- `self`: `let this = obj`
- `mut self`: `let mut this = obj`
- `&self`: `let this = &obj`
- `&mut self`
+ If `obj` is `let mut obj = ...`, use a mutable reference: `let this = &mut obj`
+ If `obj` is `let obj = &mut ...;`, perform a reborrow: `let this = &mut *obj`
