4927: Better encapsulate reverse-mapping of files to cargo targets r=matklad a=matklad
We need to find a better way to do it...
CrateGraph by itself is fine, CargoWorkspace as well, but the mapping
between the two seems arbitrary...

4925: Syntax highlighting for escape sequences in strings r=matklad a=ltentrup
I have added a new semantic token type `ESCAPE_SEQUENCE` as the LSP specification does not seem to have an appropriate token type. This may actually be a regression for some users, as the TextMate Rust grammar has a scope `constant.character.escape.rust` which highlights escape sequences (which caused problems with semantic highlighting, see #4138).
Fixes#2604.

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?

4909: Anchor file-system operations to the file, and not to the source root. r=matklad a=matklad

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!

4876: Syntactic highlighting of NAME_REF for injections r=matklad a=ltentrup
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.
Follow up of #4683.
Fixes#4809.

If a relative path is found as part of Crate.root_module or Root.path, interpret it as relative to the location of the rust-project.json file.
