5002: Fix underflow panic when doctests are at top of file r=Nashenas88 a=Nashenas88
While debugging a comment at the top of a test string, I discovered that the offset calculations could underflow and panic. This only seemed to occur in tests, I assume because it's running a debug mode. The wrapping is quickly fixed later on in release mode, which is why this seems to have gone unnoticed. The new checks ensure the value is always positive or zero.

4999: SSR: Allow matching of whole macro calls r=matklad a=davidlattimore
Matching within macro calls is to come later and matching of macro calls within macro calls later still.

5000: Remove RelativePathBuf from fixture r=matklad a=matklad
The paths in fixture are not really relative (the default one is
`/main.rs`), so it doesn't make sense to use `RelativePathBuf` here.

4900: Self variant enum res fix r=BGluth a=BGluth
Fixes#4789.
This is my first PR for this project, so it's probably worth giving it an extra close look.
A few things that I wasn't sure about:
- Is `resolve_path` really the best place to perform this check? It seemed like a natural place, but perhaps there's a better place?
- When handling the new variant `PathResolution::VariantDef`, I couldn't see an obvious variant of `TypeNs` to return in `in_type_ns` for Unions and Structs.

4851: Add quickfix to add a struct field r=TimoFreiberg a=TimoFreiberg
Related to #4563
I created a quickfix for record literals first because the NoSuchField diagnostic was already there.
To offer that quickfix for FieldExprs with unknown fields I'd need to add a new diagnostic (or create a `NoSuchField` diagnostic for those cases)
I think it'd make sense to make this a snippet completion (to select the generated type), but this would require changing the `Analysis` API and I'd like some feedback before I touch that.

4903: Add highlighting support for doc comments r=matklad a=Nashenas88
The language server protocol includes a semantic modifier for documentation. This change exports that modifier for doc comments so users can choose to highlight them differently compared to regular comments.
Example:

We might as well handle them internally, via queries.
I am not sure, but it looks like the current LibraryData setup might
even predate salsa? It's not really needed and creates a bunch of
complexity.
4913: Remove debugging code for incremental sync r=matklad a=lnicola

Fixes#4904
4916: Warnings as hint or info r=matklad a=GabbeV
Fixes#4229
This PR is my second attempt at providing a solution to the above issue. My last PR(#4721) had to be rolled back(#4862) due to it overriding behavior many users expected. This PR solves a broader problem while trying to minimize surprises for the users.
### Problem description
The underlying problem this PR tries to solve is the mismatch between [Rustc lint levels](https://doc.rust-lang.org/rustc/lints/levels.html) and [LSP diagnostic severity](https://microsoft.github.io/language-server-protocol/specification#diagnostic). Rustc currently doesn't have a lint level less severe than warning forcing the user to disable warnings if they think they get to noisy. LSP however provides two severitys below warning, information and hint. This allows editors like VSCode to provide more fine grained control over how prominently to show different diagnostics.
Info severity shows a blue squiggly underline in code and can be filtered separately from errors and warnings in the problems panel.
Hint severity doesn't show up in the problems panel at all and only show three dots under the affected code or just faded text if the diagnostic also has the unnecessary tag.
### Solution
The solution provided by this PR allows the user to configure lists of of warnings to report as info severity and hint severity respectively. I purposefully only convert warnings and not errors as i believe it's a good idea to have the editor show the same severity as the compiler as much as possible.
### Open questions
#### Discoverability
How do we teach this to new and existing users? Should a section be added to the user manual? If so where and what should it say?
#### Defaults
Other languages such as TypeScript report unused code as hint by default. Should rust-analyzer similarly report some problems as hint/info by default?

Anchoring to the SourceRoot wont' work if the path is absolute:
#[path = "/tmp/foo.rs"]
mod foo;
Anchoring to a file will.
However, we *should* anchor, instead of just producing an abs path.
I can imagine a situation where, for example, rust-analyzer processes
crates from different machines (or, for example, from in-memory git
branch), where the same absolute path in different crates might refer
to different files in the end!
This commit adds a function that tries to determine the syntax highlighting class of NAME_REFs based on the usage.
It is used for highlighting injections (such as highlighting of doctests) as the semantic logic will most of the time result in unresolved references.
It also adds a color to unresolved references in HTML encoding.
4849: Make known paths use `core` instead of `std` r=matklad a=jonas-schievink
I'm not sure if this causes problems today, but it seems like it easily could, if rust-analyzer processes the libstd sources for the right `--target` and that target is a `#![no_std]`-only target.

4683: Implement syntax highlighting for doctests r=ltentrup a=ltentrup
The implementation is more complicated than the previous injection logic as the doctest comments consist of multiple ranges. The implementation extracts the doctests together with an offset-mapping, applies the syntax highlighting, and updates the text ranges.

4781: Remove redundancy in syntax highlighting tests r=matklad a=ltentrup
Follow up from #4683. Improves syntax highlighting testing by introducing a function that contains the boilerplate comparison code. Keeps the `ra_fixture` argument in the first position, thus, the editor syntax highlighting injection still works.

4748: Add an `ImportMap` and use it to resolve item paths in `find_path` r=matklad a=jonas-schievink
Removes the "go faster" queries I added in https://github.com/rust-analyzer/rust-analyzer/pull/4501 and https://github.com/rust-analyzer/rust-analyzer/pull/4506. I've checked this PR on the rustc code base and the assists are still fast.
This should fix https://github.com/rust-analyzer/rust-analyzer/issues/4515.
Note that this does introduce a change in behavior: We now always refer to items defined in external crates using paths through the external crate. Previously we could also use a local path (if for example the extern crate was reexported locally), as seen in the changed test. If that is undesired I can fix that, but the test didn't say why the previous behavior would be preferable.
