By default, `spawn` inherits stderr/stdout/stderr of the parent
process, and so, if child, for example does fcntl(O_NONBLOCK), weird
stuff happens to us.

2963: Emacs fixes r=matklad a=flodiebold
- use provided environment for runnables (finally set `RUST_BACKTRACE`)
- implement `selectAndApplySourceChange` so auto-import works 🙂

2967: Disable optimizations for some build-time crates r=matklad a=lnicola
This speeds up a release build on my laptop from 4m 13s to 3m 33s. It's a bit disappointing, but we don't get perfect parallelism during the build. The non-RA dependencies finish building around 72s as opposed to 112s.

2920: Better handle illformed node id from metadata r=matklad a=edwin0cheng
In some rare cases, deps node-id from cargo-metadata do not match its version-id, which cause a panic in `cargo-workspace.rs`. This PR try to ignore these ill-formed node id from `cargo-metadata`. An alternative is return `Err` in these cases but I think make it resilience is a better choice here.

2895: Rewrite ra_prof's profile printing r=michalt a=michalt
This changes the way we print things to first construct a mapping from
events to the children and uses that mapping to actually print things.
It should not change the actual output that we produce.
The new approach two benefits:
* It avoids a potential quadratic behavior of the previous approach.
For instance, for a vector of N elements:
```
[Message{level: (N - 1)}, ..., Message{level: 1}, Message{level: 0}]
```
we would first do a linear scan to find entry with level 0, then
another scan to find one with level 1, etc.
* It makes it much easier to improve the output in the future, because
we now pre-compute the children for each entry and can easily take
that into account when printing.

2942: Properly select a target for auto importing r=matklad a=SomeoneToIgnore
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/2932
The corresponding test has the caret placed in the beggining of the document despite the import inserted, but I don't thing I should fix it here:
* in real life, there's some text written before the import and for those cases the caret behaves normally
* it's a separate functionality that needs to be refactored anyway later (the `auto_import_text_edit`)

2937: Parse cargo output a line at a time. r=kiljacken a=kiljacken
We previously used serde's stream deserializer to read json blobs from
the cargo output. It has an issue though: If the deserializer encounters
invalid input, it gets stuck reporting the same error again and again
because it is unable to foward over the input until it reaches a new
valid object.
Reading a line at a time and manually deserializing fixes this issue,
because cargo makes sure to only outpu one json blob per line, so should
we encounter invalid input, we can just skip a line and continue.
The main reason this would happen is stray printf-debugging in
procedural macros, so we still report that an error occured, but we
handle it gracefully now.

2931: Added documentation to test_utils r=matklad a=Veetaha
Added some doc comments to test_utils functions while studying this crate. They should be all stable enough to document them.
Also some minor code relocation in `parse_fixture()` closer to its usage according to the advice of @matklad.
