This also prevents the assist from being disabled if a definition in the value namespace exists with the same name as our new struct since that won't cause a collision

6458: Qualify trait impl created by add_custom_impl assist r=matklad a=Veykril
When we find at least one trait with the same name as the derive accessible from the current module we now generate a qualified path to that trait in the generated impl.
If we don't find any we just do what was done before and emit the trait name in the generated impl.

This also seizes the opportunity to move integer literal parsing to
the syntax crate, were it logically belongs.
Note though that this is still done in an ad hoc manner -- we probably
should split kitchen sink ast::Literal into a separate APIs for
strings, ints, etc
6287: Don't replace entire module and file nodes when inserting imports r=matklad a=Veykril
This change minifies the resulting diff of import insertions by inserting or replacing the produced use tree directly through an `action` return value instead replacing the entire container node. This action has to be applied by the caller now. This unfortunately pulls the `AssistBuilder` into scope of `insert_use` back again but I tried to at least keep it away from the `insert_use` fn itself.
I'm open to more/better ideas regarding this :)

6401: Only show `self` ident when showing parameter self hints r=matklad a=Veykril
This just hints all self parameters with the `self` token, this is therefor equal to how all other parameters are displayed, but given the self param special in how its defined in a function signature it might make sense to keep the `&`/`&mut` parts as well as emitting those tokens for explict `Self` types that are taken by ref like `self: &Rc<Self>`?

If this would be more appropriate as a new test, or if the original check for an invalid path should be left, I'm happy to update.

6430: Move completions rendering into a separate module r=popzxc a=popzxc
This PR extracts rendering-related things from `Completions` structure to the new `render` module.
`render` module declares a `Render` structure (which is a generic renderer interface), `RenderContext` (interface for data/methods not required for completions generating, but required for rendering), and a bunch of smaller `*Render` structures which encapsulate logic behind rendering a certain item.
This is just a step in full separation direction, since the following this are still to be done:
- Move some data from `CompletionContext` to the `RenderContext`;
- Forbid any kind of rendering outside of `render` module;
- Extract score computing into a separate module.
This PR is already pretty big, so not to make it even harder to review I decided to split this process into several subsequent PRs.

6441: Coalesce prime_caches updates r=matklad a=jonas-schievink
This reduces the number of progress bar updates we send to the client by collapsing subsequent updates into one. This doesn't work as well as I'd hoped (which is that we end up sending *no* updates, or only `start` and `end`, when the cache is already fresh), but it does reduce the number considerably: instead of ~720 updates on the rust-analyzer codebase, we now only send ~60.
It uses the same approach that is already in use for coalescing VFS events.
Hopefully this is enough to fix https://github.com/rust-analyzer/rust-analyzer/issues/6413.

Historically, we intentinally violated JSON-RPC spec here by hard
crashing. The idea was to poke both the clients and servers to fix
stuff.
However, this is confusing for server implementors, and falls down in
one important place -- protocol extension are not always backwards
compatible, which causes crashes simply due to version mismatch. We
had once such case with our own extension, and one for semantic
tokens.
So let's be less adventerous and just err on the err side!

6351: Organized completions r=popzxc a=popzxc
This PR continues the work on refactoring of the `completions` crate.
In this episode:
- Actual completions methods are encapsulated into `completions` module, so they aren't mixed with the rest of the code.
- Name duplication was removed (`complete_attribute` => `completions::attribute`, `completion_context` => `context`).
- `Completions` structure was moved from `item` module to the `completions`.
- `presentation` module was removed, as it was basically a module with `impl` for `Completions`.
- Code approaches were a bit unified here and there.

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.

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)
```

Declaration names sounds like a name of declaration -- something you
can use for analysis. It empathically isn't, and is just a label
displayed in various UI. It's important not to confuse the two, least
we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).
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

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).
