Reading through the code for diagnostics and observing debug logs, I noticed
that diagnostics are transmitted after every change for every opened file,
even if they haven't changed (especially visible for files with no diagnostics).
This change avoids marking files as "changed" if diagnostics are the same to what
was already sent before. This will only work if diagnostics are always produced in
the same order, but from my limited testing it seems this is the case.

7703: Allow comments between newlines in chaining hints r=Veykril a=unratito
Currently, chaining hints are not generated if there are comments between newlines, which is a very common pattern:
```rust
let vec = (0..10)
// Multiply by 2
.map(|x| x * 2)
// Add 3
.map(|x| x + 3)
.collect::<Vec<i32>>();
```
Besides, it seems a bit weird that this piece of code generates a chaining hint:
```rust
let vec = (0..10)
.collect::<Vec<i32>>();
```
But this one doesn't:
```rust
let vec = (0..10)
// This is a comment
.collect::<Vec<i32>>();
```

7690: Extract `fn load_workspace(…)` from `fn load_cargo(…)` r=matklad a=regexident
Unfortunately in https://github.com/rust-analyzer/rust-analyzer/pull/7595 I forgot to `pub use` (rather than just `use`) the newly introduced `LoadCargoConfig`.
So this PR fixes this now.
It also:
- splits up `fn load_cargo` into a "workspace loading" and a "project loading" phase
- adds a `progress: &dyn Fn(String)` to allow third-parties to provide CLI progress updates, too
The motivation behind both of these is the fact that rust-analyzer currently does not support caching.
As such any third-party making use of `ra_ap_…` needs to providing a caching layer itself.
Unlike for rust-analyzer itself however a common use-pattern of third-parties is to analyze a specific target (`--lib`/`--bin <BIN>`/…) from a specific package (`--package`). The targets/packages of a crate can be obtained via `ProjectWorkspace::load(…)`, which currently is performed inside of `fn load_cargo`, effectively making the returned `ProjectWorkspace` inaccessible to the outer caller. With this information one can then provide early error handling via CLI (in case of ambiguities or invalid arguments, etc), instead of `fn load_cargo` failing with a possibly obscure error message. It also allows for annotating the persisted caches with its specific associated package/target selector and short-circuit quickly if a matching cache is found on disk, significantly cutting load times.
Before:
```rust
pub struct LoadCargoConfig {
pub cargo_config: &CargoConfig,
pub load_out_dirs_from_check: bool,
pub with_proc_macro: bool,
}
pub fn load_cargo(
root: &Path,
config: &LoadCargoConfig
) -> Result<(AnalysisHost, vfs::Vfs)> {
// ...
}
```
After:
```rust
pub fn load_workspace(
root: &Path,
config: &CargoConfig,
progress: &dyn Fn(String),
) -> Result<ProjectWorkspace> {
// ...
}
pub struct LoadCargoConfig {
pub load_out_dirs_from_check: bool,
pub with_proc_macro: bool,
}
pub fn load_cargo(
ws: ProjectWorkspace,
config: &LoadCargoConfig,
progress: &dyn Fn(String),
) -> Result<(AnalysisHost, vfs::Vfs)> {
// ...
}
```

7687: Specialization for async traits r=matklad a=arnaudgolfouse
Fixes #7669.
Adapting the parser seemed to be all that was needed, but I am not very experienced with the codebase. Is this enough ?

7620: Support control flow in `extract_function` assist r=matklad a=cpud36
Support `return`ing from outer function, `break`ing and `continue`ing outer loops when extracting function.
# Example
Transforms
```rust
fn foo() -> i32 {
let items = [1,2,3];
let mut sum = 0;
for &item in items {
<|>if item == 42 {
break;
}<|>
sum += item;
}
sum
}
```
Into
```rust
fn foo() -> i32 {
let items = [1,2,3];
let mut sum = 0;
for &item in items {
if fun_name(item) {
break;
}
sum += item;
}
sum
}
fn fun_name(item: i32) -> bool {
if item == 42 {
return true;
}
false
}
```
# Features
Supported variants
- break and function does not return => uses `bool` and plain if
- break and function does return => uses `Option<T>` and matches on it
- break with value and function does not return => uses `Option<T>` and if let
- break with value and function does return => uses `Result<T, U>` and matches on t
- same for `return` and `continue`(but we can't continue with value)
Assist does handle nested loops and nested items(like functions, modules, impls)
Try `expr?` operator is allowed together with `return Err(_)` and `return None`.
`return expr` is not allowed.
# Not supported
## Mixing `return` with `break` or `continue`
If we have e.g. a `return` and a `break` in the selected code, it is unclear what the produced code should look like.
We can try `Result<T, Option<U>>` or something like that, but it isn't idiomatic, nor it is established. Otherwise, implementation
is relatively simple.
## `break` with label
Not sure how to handle different labels for multiple `break`s.
[edit] implemented try `expr?`

7656: Implement constructor usage search for almost all items r=matklad a=Veykril
This PR moves the filering for enum constructors to the HIR, with this unprefixed variants as well as when the enum has been renamed via use will then still show up properly.
We now walk the ast of the `NameRef` up until we find a `PathExpr`(which also handles `CallExpr` for tuple-type structs and variants already) or a `RecordExpr`. For enum search we then take the `path` out of that expression and do a resolution on it to compare it with the definition enum.
With this PR we now support searching for all constructor literals, Unit-, Tuple- and Record-Structs, Unit-, Tuple- and Record-Variants as well as Unions.
There is one shortcoming due to how the search is triggered. Unit Variants constructors can't be searched as we have no position for it to kick off the search(since a comma doesn't have to exist for the last variant).
Closes #2549 though it doesn't implement it as outlined in the issue since the reference kind was removed recently, though I believe the approach taken here is better personally.

For all struct kinds, unions and enums, as well as for record- and
tuple-variants but not for unit-variants, as these have no trailing
character we can anchor the search to. Functionality wise it is
implemented though.

7643: Automatically detect the rustc-src directory (fixes #3517) r=matklad a=bnjbvr
If the configured rustcSource was not set, then try to automatically
detect a source for the sysroot rustc directory.
I wasn't sure how to do it in the case of the project.json file, though.
7663: Tolerate spaces in nix binary patching r=matklad a=CertainLach
If path to original file contains space (I.e on code insiders, where
default data directory is ~/Code - Insiders/), then there is syntax
error evaluating src arg.
Instead pass path as str, and coerce to path back in nix expression

7668: Finalize rename infra rewrite r=matklad a=Veykril
This should be the final PR in regards to rewriting rename stuff, #4290.
It addresses 3 things:
- Currently renaming import aliases causes some undesired behavior(see #5198) which is why this PR causes us to just return an error if an attempt at renaming an alias is made for the time being. Though this only prevents it from happening when the alias import is renamed, so its not too helpful.
- Fixes #6898
- If we are inside a macro file simply rename the input name node as there isn't really a way to do any of the fancy shorthand renames and similar things as for that we would have to exactly know what the macro generates and what not.
