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.

4775: Add goto def for enum variant field r=matklad a=unexge
Closes#4764. I'm not familiar with ra codebase, there might be better ways to do that 😄

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.

4729: Hover actions r=matklad a=vsrs
This PR adds a `hoverActions` LSP extension and a `Go to Implementations` action as an example:

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.
