780: Mention node.js requirement in readme r=DJMcNab a=Matthias247
I tried building rust-analyzer according to the instructions, but it failed with a very non-descriptive error:
> will run: npm ci
> Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }
It took me a while to figure out I had an outdated node version installed, which didn't support `npm ci`. I think mentioning the requirement explicitly might prevent others from running into the same issue.

762: "Dumb" auto import assist r=matklad a=eulerdisk
This adds a new assist to "add xxx::yyy to the current file" when the cursor is on a PATH. It manages correctly nested imports,`self` keyword and creates new nested imports if necessary. [See the tests]
It doesn't use name resolution so in that sense is 'dumb', but I have plans to do that. That in the future will be useful to auto import trait names in autocompletion for example.
It can easily be extended to provide multiple actions to select in which scope to import. That's another thing I plan to do.
@matklad I copied some indentation code from `ide_light`, I don't know at the moment if/how you want to refactor that code. This assist was meant to be in `ide_light`.

774: Batch crate & command r=matklad a=flodiebold
This adds a new crate, `ra_batch`, which is intended for scenarios where you're loading a workspace once and then running some analyses using the HIR API. Also, it adds a command to `ra_cli` which uses that to type-check all crates in a workspace and print some statistics:
E.g. in rust-analyzer:
```
> $ time target/release/ra_cli analysis-stats
Database loaded, 21 roots
Crates in this dir: 28
Total modules found: 231
Total declarations: 3694
Total functions: 2408
Total expressions: 47017
Expressions of unknown type: 19826 (42%)
Expressions of partially unknown type: 4482 (9%)
target/release/ra_cli analysis-stats 3,23s user 0,60s system 100% cpu 3,821 total
```
Or in rust-lang/rust:
```
> $ time ../opensource/rust-analyzer/target/release/ra_cli analysis-stats
Database loaded, 77 roots
Crates in this dir: 130
Total modules found: 1820
Total declarations: 35038
Total functions: 25914
Total expressions: 753678
Expressions of unknown type: 337975 (44%)
Expressions of partially unknown type: 92314 (12%)
../opensource/rust-analyzer/target/release/ra_cli analysis-stats 13,45s user 2,08s system 100% cpu 15,477 total
```
~This still needs a test. Type-checking all of rust-analyzer sadly takes almost a minute when compiled in debug mode 😅 So I'll need to add something simpler (maybe just looking at a few modules).~

776: Add support for a seperate output channel for trace messages r=DJMcNab a=DJMcNab
See https://github.com/Microsoft/vscode-languageserver-node/pull/444
I am just working on testing this now, but I think it should work.

770: Fix introduce var duplicating newlines r=matklad a=vipentti
This fixes#713.
If the block before the statement we want to use introduce var on, had empty
lines these empty lines would also be added between the let-statement and
the current line where the new variable is used.
This fixes that by trimming excess newlines from the start of the indent chunk
and simply adding a single newline (when the chunk had newlines) between the
let-statement and the current statement. If there were no newlines this
matches the previous behaviour.

773: Crash fixes r=matklad a=flodiebold
This fixes a bunch of crashes found while running type inference on the whole rustc repo 😅
- avoid infinite recursion with ref bind patterns
- avoid another infinite recursion
- handle literal patterns, add a new LITERAL_PAT syntax node for this
- fix an expect that's wrong on some invalid code

771: update notify with fix for hight cpu usage r=matklad a=vemoo
Should fix the ocasional 100% CPU hangs.
I've tried `yes > test.rs` which would cause it before, and now on my computer it stays below 10%, and stops as soon as I interrupt the command, unlike previously which would stay at 100% for a while.

767: Extract project model to separate crate r=matklad a=flodiebold
I'm looking into creating a separate crate that would allow getting a HIR db for a project for 'batch' analyses, and this seems to be an obvious first step. We'd probably want to change the error handling to not rely on failure, though, right?
