6033: Make name resolution resolve proc macros instead of relying purely on the build system r=matklad a=jonas-schievink
This makes name resolution look at proc-macro declaration attributes like `#[proc_macro_derive]` and defines the right proc macro in the macro namespace, fixing unresolved custom derives like `thiserror::Error` (which can cause false positives, now that we emit diagnostics for unresolved imports).
This works even when proc-macro support is turned off, in which case we fall back to a dummy expander that always returns an error. IMO this is the right way to handle at least the name resolution part of proc. macros, while the *expansion* itself should rely on the build system to build and provide the macro DLL. It does mean that they may go out of sync, but we can provide diagnostics if that happens (something like "could not find macro X in crate Y – ensure that all files of crate Y are saved").
I think it is valuable to be able to reason about proc macros even when we can't expand them, since proc macro expansion can break between Rust releases or users might not want to turn it on for performance reasons. It allows us to provide better diagnostics on any proc macro invocation we're not expanding (like a weak warning that informs the user that proc macro support is turned off, or that it has been disabled because the server crashed).

6073: Dont unnecessarily unnest imports r=matklad a=Veykril
Fixes#6071
This has the side effect that paths that refer to items inside of the current module get prefixed with `self`. Changing this behavior is unfortunately not straightforward should it be unwanted, though I don't see a problem with this as prefixing imports like this with `self` is what I do personally anyways 😅. You can see what I mean with this in one of the tests which had to be changed in `crates/ssr/src/tests.rs`.
There is one test that i still have to look at though, ~~which I by accident pushed with `#[ignore]` on it~~, which is `different_crate_renamed`, for some reason this now doesn't use the crate alias. This also makes me believe that aliases in general will break with this. So maybe this is not as straight forwards as I'd hoped for, but I don't really know how aliases work here.
Edit: The failing test should work now

6055: Add ok postfix completion r=matklad a=mullr
Wrapping values in `Ok(...)` is so pervasive that it seems reasonable for it to
have its own postfix completion.

6062: Bump smol_str from 0.1.16 to 0.1.17 r=matklad a=woshilapin
When I built `rust-analyzer` today, I noticed the following warnings.
```
warning: use of deprecated item 'syntax::SmolStr::new_inline_from_ascii': Use `new_inline` instead
--> crates/mbe/src/syntax_bridge.rs:639:30
|
639 | ... (SmolStr::new_inline_from_ascii(1, &[punct.char as u8]), punct.id)
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= note: `#[warn(deprecated)]` on by default
warning: 1 warning emitted
```
So I thought it would be a nice small PR.

6061: Allow to use a Github Auth token for fetching releases r=matklad a=Matthias247
This change allows to use a authorization token provided by Github in
order to fetch metadata for a RA release. Using an authorization token
prevents to get rate-limited in environments where lots of RA users use
a shared client IP (e.g. behind a company NAT).
The auth token is stored in `ExtensionContext.globalState`.
As far as I could observe through testing with a local WSL2 environment
that state is synced between an extension installed locally and a remote
version.
The change provides no explicit command to query for an auth token.
However in case a download fails it will provide a retry option as well
as an option to enter the auth token. This should be more discoverable
for most users.
Closes#3688

5846: Add references to fn args during completion r=matklad a=adamrk
When completing a function call, if there is an argument taken as a ref or mut ref which matches the name and type of a variable in scope, we will insert a `&` or `&mut` when filling in the function arguments. This addresses https://github.com/rust-analyzer/rust-analyzer/issues/5449.
E.g.
```rust
fn foo(x: &i32) {}
fn main() {
let x = 5;
foo # completing foo here generates `foo(&x)` now instead of `foo(x)`
}
```

The previous version would have interpreted an empty token as
an abort of the dialog and would have not properly cleared the token.
This is now fixed by checking for `undefined` for a an abort and
by setting the token to `undefined` in order to clear it.

6043: Allow missing trait members assist without needing braces r=matklad a=M-J-Hooper
Assist to complete missing items when implementing a trait does not appear without impl def braces (see #5144 ).
The reason behind this was that this assist is based on `ast::AssocItemList` which only appears in the AST after the braces are added to the impl def.
Instead of relying on and replacing the item list, we now instead replace the entire `ast::Impl` and add the item list if its missing.
