4405: Make some stuff public so that they can be reused by other tools r=pksunkara a=pksunkara
So, my little experiment of building a code analysis tool using rust-analyzer is successful. I am going to proceed to build the tool now. This PR makes the needed things public.
I know there were some things about trying to change stuff regarding loading workspaces, which would make it more easier for other tools to reuse. But, until then, it should be okay using this `load_cargo` fn.
Btw, if I were publish my tool, I would need the `ra` crates to be released. Since @matklad told me that he doesn't want to care about breaking stuff, I would propose the following.
Every monday, during the weekly release, we release a new pre v1 minor version of all the crates. That way, we don't need to care about breaking stuff but still have rust-analyzer on crates.io.
I made https://github.com/pksunkara/cargo-workspaces to help release workspace crates easily.
So, coming week, we start with `0.1.0`, then week after that, we release `0.2.0` and then `0.3.0` etc.. until we decide on `1.0.0` which is probably when the compiler team also starts using the crates. There is no limit to the minor versions (we can even have `0.150.0` or `0.1500.0`), so I don't see anything wrong with this strategy.

4083: Smol documentation for ast nodes r=matklad a=Veetaha
There is a tremendous amount of TODOs to clarify the topics I am not certain about.
Please @matklad, @edwin0cheng review carefully, I even left some mentions of your names in todos to put your attention where you most probably can give comments.
In order to simplify the review, I separated the codegen (i.e. changes in `ast/generated/nodes.rs`) from `ast_src` changes (they in fact just duplicate one another) into two commits.
Also, I had to hack a little bit to let the docs be generated as doc comments and not as doc attributes because it's easier to read them this way and IIRC we don't support hints for `#[doc = ""]` attributes for now...
Closes#3682

This reverts commit 7a49165f5d.
MacroStmts ast node is not used by itself, but it pertains
to SyntaxNodeKind MACRO_STMTS that is used by ra_paser, so
even tho the node itself is not used, it is better to keep it
with a FIXME to actually add a doc comment when it becomes useful.

4397: Textmate cooperation r=matklad a=georgewfraser
This PR tweaks the fallback TextMate scopes to make them more consistent with the existing grammar and other languages, and edits the builtin TextMate grammar to align with semantic coloring. Before is on the left, after is on the right:
<img width="855" alt="Screen Shot 2020-05-10 at 1 45 51 PM" src="https://user-images.githubusercontent.com/1369240/81512320-a8be7e80-92d4-11ea-8940-2c03f6769015.png">
**Use keyword.other for regular keywords instead of keyword**. This is a really peculiar quirk of TextMate conventions, but virtually *all* TextMate grammars use `keyword.other` (colored blue in VSCode Dark+) for regular keywords and `keyword.control` (colored purple in VSCode Dark+) for control keywords. The TextMate scope `keyword` is colored like control keywords, not regular keywords. It may seem strange that the `keyword` scope is not the right fallback for the `keyword` semantic token, but TextMate has a long and weird history. Note how keywords change from purple back to blue (what they were before semantic coloring was added):
**(1) Use punctuation.section.embedded for format specifiers**. This aligns with how Typescript colors formatting directives:
<img width="238" alt="Screen Shot 2020-05-09 at 10 54 01 AM" src="https://user-images.githubusercontent.com/1369240/81481258-93b5f280-91e3-11ea-99c2-c6d258c5bcad.png">
**(2) Consistently use `entity.name.type.*` scopes for type names**. Avoid using `entity.name.*` which gets colored like a keyword.
**(3) Use Property instead of Member for fields**. Property and Member are very similar, but if you look at the TextMate fallback scopes, it's clear that Member is intended for function-like-things (methods?) and Property is intended for variable-like-things.
**(4) Color `for` as a regular keyword when it's part of `impl Trait for Struct`**.
**(5) Use `variable.other.constant` for constants instead of `entity.name.constant`**. In the latest VSCode insiders, variable.other.constant has a subtly different color that differentiates constants from ordinary variables. It looks close to the green of types but it's not the same---it's a new color recently added to take advantage of semantic coloring.
I also made some minor changes that make the TextMate scopes better match the semantic scopes. The effect of this for the user is you observe less of a change when semantic coloring "activates". You can see the changes I made relative to the built-in TextMate grammar here:

4421: Find references to a function outside module r=flodiebold a=montekki
Fixes#4188
Yet again, it looks like although the code in
da1f316b02/crates/ra_ide_db/src/search.rs (L128-L132)
may be wrong, it is not hit since the `vis` is `None` at this point. The fix is similar to the #4237 case: just add another special case to `Definition::visibility()`.

This fixes an issue where the following code sample would fail to infer
the type contained in the option:
```rust
fn main() {
let mut end = None; // TODO: Fix inference for this in RA
loop {
end = Some(true);
}
}
```
4175: Introduce HirDisplay method for rendering source code & use it in add_function assist r=flodiebold a=TimoFreiberg
Next feature for #3639.
So far the only change in the new `HirDisplay` method is that paths are qualified, but more changes will be necessary (omitting the function name from function types, returning an error instead of printing `"{unknown}"`, probably more).
Is that approach okay?

E.g. in
```rust
match x {
1 => function1,
2 => function2,
}
```
we need to try coercing both to pointers. Turns out this is a special case in
rustc as well (see the link in the comment).
4377: Implement better handling of divergence r=matklad a=flodiebold
Divergence here means that for some reason, the end of a block will not be reached. We tried to model this just using the never type, but that doesn't work fully (e.g. in `let x = { loop {}; "foo" };` x should still have type `&str`); so this introduces a `diverges` flag that the type checker keeps track of, like rustc does. We also add some checking for `break`, but no support for break-with-value or labeled breaks yet.

4329: Look for `cargo`, `rustc`, and `rustup` in standard installation path r=matklad a=cdisselkoen
Discussed in #3118. This is approximately a 90% fix for the issue described there.
This PR creates a new crate `ra_env` with a function `get_path_for_executable()`; see docs there. `get_path_for_executable()` improves and generalizes the function `cargo_binary()` which was previously duplicated in the `ra_project_model` and `ra_flycheck` crates. (Both of those crates now depend on the new `ra_env` crate.) The new function checks (e.g.) `$CARGO` and `$PATH`, but also falls back on `~/.cargo/bin` manually before erroring out. This should allow most users to not have to worry about setting the `$CARGO` or `$PATH` variables for VSCode, which can be difficult e.g. on macOS as discussed in #3118.
I've attempted to replace all calls to `cargo`, `rustc`, and `rustup` in rust-analyzer with appropriate invocations of `get_path_for_executable()`; I don't think I've missed any in Rust code, but there is at least one invocation in TypeScript code which I haven't fixed. (I'm not sure whether it's affected by the same problem or not.) a4778ddb7a/editors/code/src/cargo.ts (L79)
I'm sure this PR could be improved a bunch, so I'm happy to take feedback/suggestions on how to solve this problem better, or just bikeshedding variable/function/crate names etc.
