7891: Improve handling of rustc_private r=matklad a=DJMcNab
This PR changes how `rust-analyzer` handles `rustc_private`. In particular, packages now must opt-in to using `rustc_private` in `Cargo.toml`, by adding:
```toml
[package.metadata.rust-analyzer]
rustc_private=true
```
This means that depending on crates which also use `rustc_private` will be significantly improved, since their dependencies on the `rustc_private` crates will be resolved properly.
A similar approach could be used in #6714 to allow annotating that your package uses the `test` crate, although I have not yet handled that in this PR.
Additionally, we now only index the crates which are transitive dependencies of `rustc_driver` in the `rustcSource` directory. This should not cause any change in behaviour when using `rustcSource: "discover"`, as the source used then will only be a partial clone. However, if `rustcSource` pointing at a local checkout of rustc, this should significantly improve the memory usage and lower indexing time. This is because we avoids indexing all crates in `src/tools/`, which includes `rust-analyzer` itself.
Furthermore, we also prefer named dependencies over dependencies from `rustcSource`. This ensures that feature resolution for crates which are depended on by both `rustc` and your crate uses the correct set for analysing your crate.

I have tested this in [priroda](https://github.com/oli-obk/priroda/), and it provides a significant improvement to the development experience (once I give `miri` the required data in `Cargo.toml`)
Todo:
- [ ] Documentation
This is ready to review, and I will add documentation if this would be accepted (or if I get time to do so anyway)

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

`vim-lsp` is another popular LSP client for Vim. And, as there is no
`rust-analyzer` specific UI, it is non-trivial to figure out how the
initial configuration is performed.
Use `npm ci` instead of `npm install`. `npm install` will overwrite
the lock file if you have a newer npm version than the one that
generated the package-lock.json
7457: Add no-buffering file logging and wait for a debugger option. r=vsrs a=vsrs
Adds two command line flags: `--no-buffering` and `--wait-dbg`.
Not sure if someone else needs this, but personally I found both flags extremely useful trying to figure out why RA does not work with Visual Studio. Or better to say why Visual Studio does not work with RA.

Rather than eagerly converting JSON, we losslessly keep it as is, and
change the shape of user-submitted data at the last moment.
This also allows us to remove a bunch of wrong Defaults
7068: Add VSCode command to view the hir of a function body r=theotherphil a=theotherphil
Will fix https://github.com/rust-analyzer/rust-analyzer/issues/7061. Very rough initial version just to work out where I needed to wire everything up.
@matklad would you be happy merging a hir visualiser of some kind? If so, do you have any thoughts on what you'd like it show, and how?
I've spent very little time on this thus far, so I'm fine with throwing away the contents of this PR, but I want to avoid taking the time to make this more polished/interactive/useful only to discover that no-one else has any interest in this functionality.
