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.

2887: Initial auto import action implementation r=matklad a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/2180
Adds an auto import action implementation.
This implementation is not ideal and has a few limitations:
* The import search functionality should be moved into a separate crate accessible from ra_assists.
This requires a lot of changes and a preliminary design.
Currently the functionality is provided as a trait impl, more on that here: https://github.com/rust-analyzer/rust-analyzer/issues/2180#issuecomment-575690942
* Due to the design desicion from the previous item, no doctests are run for the new aciton (look for a new FIXME in the PR)
* For the same reason, I have to create the mock trait implementaion to test the assist
* Ideally, I think we should have this feature as a diagnostics (that detects an absense of an import) that has a corresponding quickfix action that gets evaluated on demand.
Curretly we perform the import search every time we resolve the import which looks suboptimal.
This requires `classify_name_ref` to be moved from ra_ide, so not done currently.
A few improvements to the imports mechanism to be considered later:
* Constants like `ra_syntax::SyntaxKind::NAME` are not imported, because they are not present in the database
* Method usages are not imported, they are found in the database, but `find_use_path` does not return any import paths for them
* Some import paths returned by the `find_use_path` method end up in `core::` or `alloc::` instead of `std:`, for example: `core::fmt::Debug` instead of `std::fmt::Debug`.
This is not an error techically, but still looks weird.
* No detection of cases where a trait should be imported in order to be able to call a method
* Improve `auto_import_text_edit` functionality: refactor it and move away from the place it is now, add better logic for merging the new import with already existing imports

2899: Provide more runners for potential tests r=matklad a=SomeoneToIgnore
Based on the https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Runners.20for.20custom.20test.20annotations discussion.
Adds a test runner for every method that has an annotation that contains `test` word in it, allowing to run tests annotated with custom testing annotations such as `#[tokio::test]`, `#[test_case(...)]` and others at costs of potentially emitting some false-positives.

@matklad mentioned this might be a good idea.
So the general idea is that we don't really need the lock, as we can
just clone the check watcher state when creating a snapshot. We can then
use `Arc::get_mut` to get mutable access to the state from `WorldState`
when needed.
Running with this it seems to improve responsiveness a bit while cargo
is running, but I have no hard numbers to prove it. In any case, a
serialization point less is always better when we're trying to be
responsive.
2877: "Insert explicit type " assist fix#2869, fix typo r=matklad a=TomasKralCZ
So this was quite straightforward. I basically looked at how the other assists work and tried doing something simillar. I also fixed a typo in the other assist.

Previously `ra_prof` wouldn't actually print the unaccounted time in
some cases.
We would print, for instance, this:
```
5ms - foo
2ms - bar
```
instead of:
```
5ms - foo
2ms - bar
3ms - ???
```
The fix is to properly handle the case when an entry has 0 children
instead of using the `last` variable.
