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.
Fixes#2935

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.

2923: Don't do check progress update for fresh crates r=matklad a=kiljacken
Skip sending progress updates for crates that aren't getting checked.

2916: Buffer reads from cargo check's stdout r=matklad a=lnicola
`Stdio::piped()` is unbuffered, which caused RA to read the output of `cargo check` one byte at a time (out of 114KB in my test).
This isn't obviously faster on my system, but making fewer syscalls sounds like a good idea.

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.

2872: Upgrade Chalk r=matklad a=flodiebold
This is just keeping track of the changes required to upgrade Chalk; currently we can't really merge it since it breaks opaque types.
Now also makes use of the newly introduced `solve_limited` to implement fuel.

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
