The extra allocation for message should not matter here at all, but
using a static string is just as ergonomic, if not more, and there's
no reason to write deliberately slow code
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.

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.

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.

2924: Modify ordering of drops in check watcher to only ever have one cargo r=matklad a=kiljacken
Due to the way drops are ordered when assigning to a mutable variable we
were launching a new cargo sub-process before letting the old one quite.
By explicitly replacing the original watcher with a dummy first, we
ensure it is dropped and the process is completed, before we start the
new process.

2810: Improves reference search by StructLiteral r=mikhail-m1 a=mikhail-m1
Hey, I've made some changes to improve search for struct literals, now it works for `struct Foo<|> {`, `struct Foo <|>{`, `struct Foo<|>(`. Unfortunately tuple creation is represented as a call expression, so for tuples it works only is search is started in a tuple declaration. It leads to incorrect classification of function calls during search phase, but from user perspective it's not visible and works as expected. May be it worth to add a comment or rename it to remove this misleading classification. Issue #2549.
