2981: vscode: Add ability to call onEnter without overriding "type". r=matklad a=71
Before this PR, the only way to get enhanced typing (right now, only with `onEnter`) was to override VS Code's `type` command. This leads to issues with extensions like [VsCodeVim](https://github.com/VSCodeVim/Vim) that need to override `type` as well.
This PR adds an additional command, `onEnter`. This command can be used with the following keybinding, which allows the user to get smart `onEnter` behavior without overriding `type`.
```json
{
"key": "enter",
"command": "rust-analyzer.onEnter",
"when": "editorTextFocus && editorLangId == rust"
}
```

2911: Implement collecting errors while tokenizing r=matklad a=Veetaha
Now we are collecting errors from `rustc_lexer` and returning them in `ParsedToken { token, error }` and `ParsedTokens { tokens, errors }` structures **([UPD]: this is now simplified, see updates bellow)**.
The main changes are introduced in `ra_syntax/parsing/lexer.rs`. It now exposes the following functions and types:
```rust
pub fn tokenize(text: &str) -> ParsedTokens;
pub fn tokenize_append(text: &str, parsed_tokens_to_append_to: &mut ParsedTokens);
pub fn first_token(text: &str) -> Option<ParsedToken>; // allows any number of tokens in text
pub fn single_token(text: &str) -> Option<ParsedToken>; // allows only a single token in text
pub struct ParsedToken { pub token: Token, pub error: Option<SyntaxError> }
pub struct ParsedTokens { pub tokens: Vec<Token>, pub errors: Vec<SyntaxError> }
pub enum TokenizeError { /* Simple enum which reflects rustc_lexer tokenization errors */ }
```
In the first commit I implemented it with iterators, but then decided that since this crate is ad hoc for `rust-analyzer` and we clearly see the places of its usage it would be better to simplify it to vectors.
This is currently WIP, because I want to add tests for error messages generated by the lexer.
I'd like to listen to you thoughts how to define these tests in `ra_syntax/test-data` dir.
Related issues: #223
**[UPD]**
After the PR review the API was simplified:
```rust
pub fn tokenize(text: &str) -> (Vec<Token>, Vec<SyntaxError>);
// Both lex functions do not check for unescape errors
pub fn lex_single_syntax_kind(text: &str) -> Option<(SyntaxKind, Option<SyntaxError>)>;
pub fn lex_single_valid_syntax_kind(text: &str) -> Option<SyntaxKind>;
// This will be removed in the next PR in favour of simlifying `SyntaxError` to `(String, TextRange)`
pub enum TokenizeError { /* Simple enum which reflects rustc_lexer tokenization errors */ }
// this is private, but may be made public if such demand would exist in future (least privilege principle)
fn lex_first_token(text: &str) -> Option<(Token, Option<SyntaxError>)>;
```

3003: Remove rollup-typescript r=matklad a=matklad
It seems like just calling typescript directly is simpler and more reliable?
@Veetaha what do you think about this approach?

2959: Rework how we send diagnostics to client r=matklad a=kiljacken
The previous way of sending from the thread pool suffered from stale diagnostics due to being canceled before we could clear the old ones.
The key change is moving to sending diagnostics from the main loop thread, but doing all the hard work in the thread pool. This should provide the best of both worlds, with little to no of the downsides.
This should hopefully fix a lot of issues, but we'll need testing in each individual issue to be sure.
