7071: Pass --all-targets to "cargo check" when discovering external resources r=matklad a=WasabiFan
There is a repro case and background in the linked issue.
In short, the goal of this MR is to allow rust-analyzer to discover proc-macros which come from your tests (including, most importantly, dev-dependencies).
By default, `cargo check` implies the equivalent of `--lib --bins`, meaning it'll check your libraries and binaries -- but not tests! This means proc-macros (or, I guess, build scripts as well) weren't discovered by rust-analyzer if they came from tests.
One solution would be to manually add `--lib --bins --tests` (i.e., just augment the effective options to include tests). However, in this MR, I threw in `--all-targets`, which [according to the docs](https://doc.rust-lang.org/cargo/commands/cargo-check.html#target-selection) implies `--benches --examples` too. I have absolutely no idea what repercussions that will have on rust-analyzer for other projects, nor do I know if it's a problem that build scripts will now be discovered for tests/examples/benches. But I am not aware of a reason you _wouldn't_ want to discover these things in your examples too.
I think the main drawback of this change is that it will likely slow down the `cargo check`. At a minimum, it'll now be checking your tests _and_ their dependencies. The `cargo check` docs also say that including `--tests` as I have here may cause your lib crate to be built _twice_, once for the normal target and again for unit tests. My reading of that caveat suggests that "building twice" means it's built once for the tests _inside_ your lib, with a test profile, and again for any consumers of your lib, now using a normal release profile or similar. This doesn't seem surprising.
Very minor caveat: `--tests` will not include tests within a binary if it has `test = false` set in `Cargo.toml`. (I discovered this manually by trial-and-error, but hey, it actually says that in the docs!) This is likely not an issue, but _does_ mean that if you are -- for whatever reason -- disabling tests like that and then manually specifying `cargo test --package <...> --bin <...>` to run them, rust-analyzer will remain unaware of proc-macros in your tests.
I have confirmed this fixes the original issue in my sandbox example linked in #7034 and in my own project in which I originally discovered this. I've left it configured as my default RA language server and will report back if I notice any unexpected side-effects.
Fixes#7034

7107: add working dir to cargo metadata fail messages r=matklad a=lf-
Context: I was having an error in my workspace config that I couldn't figure out without this added output. In particular, I have a Code workspace with a docs folder and one of my top level crates [which each have their own custom target], which was picking up the Cargo workspace level Cargo.toml incorrectly [which in my project should not ever be used for the editor], and ultimately had to override it with `linkedProjects`.
Here's a sample of the changed output:
```
[INFO rust_analyzer::main_loop] handle_event(Workspaces([Err(Failed to read Cargo metadata from Cargo.toml file /home/jade/dev/mu/Cargo.toml, cargo 1.50.0-nightly (75d5d8cff 2020-12-22)

7055: Install rustfmt if needed during formatting request r=matklad a=kinnison
In order to fix#6052 and to fix#4249 this PR installs `rustfmt` using `rustup` if `rustfmt --help` fails.
In theory we ought to memoise the attempts (both the `--help` and the installation) so that we don't keep retrying something which will fail (e.g. if nightly is missing rustfmt), but this is a first-pass for opinions.
In order to make it possible to notify the user of what happened, I added a facility for `GlobalStateSnapshot` to send *messages* to the client indicating what happened. There may be a cleaner way to do this as well but I wasn't sure exactly what might be best given this is my first time in this codebase.
It may be worth, longer term, working with `rustup` to provide a way to detect a missing component binary since `rustup` returns `1` if `rustfmt` is not installed, which is not ideal.

In an attempt to fix#6052 and #4249 this attempts to detect
if rustfmt is a rustup proxy which isn't installed, and reports
the error message to the user for them to fix.
In theory this ought to be memoised but for now it'll do as-is.
Future work might be to ask the user if they would like us to
trigger the installation (if possible).

7091: Add an option for extra env vars in the Code extension r=lf- a=lf-
I was debugging some issues with the RA extension around getting `cargo check` to work and it was particularly frustrating to get the RA_LOG variable set on the server since I had to change it in a login file. This should make that easier.

Inspire by #5426 , this PR refactor out the parsing code such that it only parsed on `mbe::Rule`, but not on invocations.
However, it just improve the overall performance unnoticeablely :(

7064: Ignore qualifiers when doing autoimport completions lookup r=lnicola a=SomeoneToIgnore
A follow-up of https://github.com/rust-analyzer/rust-analyzer/pull/6918#issuecomment-748511151 and the PR itself.
Tweaks the `import_map` query api to be more flexible with the ways to match against the import path and now fuzzy imports search in names only.
This had improved the completion speed for me locally in ~5 times for `fuzzy_completion` span time, but please recheck me here.
IMO we're fast and presice enough now, so I've added the modules back to the fuzzy search output.
Also tweaks the the expect tests to display functions explicitly, to avoid confusing "duplicate" results.

7059: Special case $_ in meta var instead of treat it as ident in mbe r=lnicola a=edwin0cheng
In #6929, we treat '_' as an ident but rustc is only allow it in some special places (e.g. meta var in mbe , type, pat etc).
This PR rollback that and we only make '$_' works in meta var matching.
Fixes#7056
