3162: Feature: vscode always downloads only the matching ra_lsp_server version r=matklad a=Veetaha
I tried to separate logically connected changes into separate commits, so enjoy!
Now TypeScript extension saves installed binary version in global state and always checks that the installed binary version equals the version of the TypeScript extension itself (to prevent version drifts).
Also, changed `fetchLatestArtifactReleaseInfo()` to `fetchArtifactReleaseInfo()` that takes an optional release tag (when not specified fetches the latest release). The version without a release tag will be useful in the future when adding auto-checking for updates.
I decided not to do `Download latest language server` command (I have stated the rationale for this in #3073) and let the extension itself decide which version of the binary it wants. This way the users will be able to get the latest `ra_lsp_server` binary after the approaching 2020-02-17 release, without having to manually delete the outdated one from `~/.config/Code/User/globalStorage/matklad.rust-analyzer`!
Closes#3073

3131: vscode: simplified config and to removed one source of truth of default values r=matklad a=Veetaha
Though not intended initially, the implementation of config design is alike [dart's one](https://github.com/Dart-Code/Dart-Code/blob/master/src/extension/config.ts) as pointed by @matklad in PM.

3137: Do not register all proposed features r=matklad a=kjeremy
Instead only opt-in to CallHierarchy since it has a vscode API but LSP support
is still proposed.
Discovered while working on SemanticTokens which does not have a vscode API
and is still in the proposed state. Somehow enabling it would crash the
language server.

3053: Feature: downloading lsp server from GitHub r=matklad a=Veetaha
This is currently very WIP, I may need to change this and that, add "download language server command", logging stuff (for future bug reports), etc., but it already works.
Also didn't test this on windows yet and mac (don't have the latter)
The quirks:
* Downloaded binary doesn't have executable permissions by default, that's why we ~~`chmod 111`~~ (**[UPD]** `chmod 755` as per @lnicola [suggestion](https://github.com/rust-analyzer/rust-analyzer/pull/3053#discussion_r376694456)) for it.
* To remove installed binary run `rm /${HOME}/.config/Code/User/globalStorage/matklad.rust-analyzer/ra_lsp_server-linux`, ~~note that `-f` flag is necessary, because of `111` permissions (I think this should be changed)~~ (**[UPD]** --force is no longer needed due to 755 permissions).
I also tried to keep things simple and not to use too many dependencies, all the ones added have 0 dependencies, (`ts-not-nil` is my personal npm package, that imitates `unwrap()` in TypeScript)
**[UPD]** I reduced throttle latency of progress indicator to 200ms for smoother UX
// TODO:
- [x] ~~Add `Rust Analyzer: Download latest language server` vscode command.~~ **[UPD]**: having reviewed the code and estimated available options I concluded that this feature requires too many code changes, I'd like to extract this into a separate PR after we merge this one.
- [x] Add some logging for future debugging
- [x] ~~Gracefully handle the case when language server is not available (e.g. no internet connection, user explicitly rejected the download, etc.)~~ **[UPD]** Decided to postpone better implementation of graceful degradation logic as per [conversation](https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Deployment.20and.20installation/near/187758550).
Demo (**[UPD]** this is a bit outdated, but still mainly reflects the feature):

2979: vscode: now we are actually using tslib r=matklad a=Veetaha
We had an incorrect setup where `tslib` was in `devDependencies`.
FYI:
tslib is a runtime dependency, it contains functions that are used by transpiled JavaScript in order not to inline them in each file.
For example:
```ts
// foo.ts (source code)
import * as foo from "foo";
// ---------------------------
// foo.js (compiled output)
"use strict";
var __importStar = (this && this.__importStar) || function (mod) {
if (mod && mod.__esModule) return mod;
var result = {};
if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result["default"] = mod;
return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
const foo = __importStar(require("foo"));
```
As you see, `tsc` generated that `__importStar` helper function in compiled output. And it generates it per each file if you don't enable `"importHelpers": true`. Now with `importHelpers` enabled we get the following picture:
```ts
// foo.ts (source code)
import * as foo from "foo";
// ---------------------------
// foo.js (compiled output)
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const tslib_1 = require("tslib");
const foo = tslib_1.__importStar(require("foo"));
```
It saves some bundle size, but I am not entirely sure wheter we want that. Discussions are welcome!

2964: Improve responsiveness of the cargo check status label r=matklad a=lnicola
This is still not ideal because the label displays the crate that was just checked, not the one that's currently being checked. But it should give the impression of being faster.

2963: Emacs fixes r=matklad a=flodiebold
- use provided environment for runnables (finally set `RUST_BACKTRACE`)
- implement `selectAndApplySourceChange` so auto-import works 🙂

2967: Disable optimizations for some build-time crates r=matklad a=lnicola
This speeds up a release build on my laptop from 4m 13s to 3m 33s. It's a bit disappointing, but we don't get perfect parallelism during the build. The non-RA dependencies finish building around 72s as opposed to 112s.
