I implemented the reverse mapping (when you hover in the rust editor), but it seems overcomplicated, so I removed it

Sometimes my RA debugging workflow breaks because `.dbg` is applied to the variable that is used later in the code.

This cancel is unnecessary since we cancel the previous inlay hints requests in `fetchHints()` method itself. This is not a hard error, we just called cancel() 2 times.

The primary focus here on simplification:
* local simplification of data structures and control-flow: using union of strings instead of an enum, using unwrapped GitHub API responses
* global simplification of control flow: all logic is now in `main.ts`, implemented as linear functions without abstractions. This is stateful side-effective code, so arguments from [Carmack](http://number-none.com/blow/john_carmack_on_inlined_code.html) very much apply. We need all user interractions, all mutations, and all network requests to happen in a single file.
* as a side-effect of condensing everything to functions, we can get rid of various enums. The enums were basically a reified control flow:
```
enum E { A, B }
fn foo() -> E {
if cond { E::A } else { E::B }
}
fn bar(e: E) {
match e {
E::A => do_a(),
E::B => do_b(),
}
}
==>>
fn all() {
if cond { do_a() } else { do_b() }
}
```
* simplification of model: we don't need to reinstall on settings update, we can just ask the user to reload, we don't need to handle nightly=>stable fallback, we can ask the user to reinstall extension, (todo) we don't need to parse out the date from the version, we can use build id for nightly and for stable we can write the info directly into package.json.
Co-authored-by: Aleksey Kladov <aleksey.kladov@gmail.com>
Everything now happens in main.ts, in the bootstrap family of
functions. The current flow is:
* check everything only on extension installation.
* if the user is on nightly channel, try to download the nightly
extension and reload.
* when we install nightly extension, we persist its release id, so
that we can check if the current release is different.
* if server binary was not downloaded by the current version of the
extension, redownload it (we persist the version of ext that
downloaded the server).
3534: Feature: vscode impl nightlies download and installation r=Veetaha a=Veetaha
I need to test things more, but the core shape of the code is quite well-formed.
The main problem is that we save the release date only for nightlies and there are no means to get the release date of the stable extension (i.e. for this we would need to consult the github releases via a network request, or we would need to somehow save this info into package.json or any other file accessible from the extension code during the deployment step, but this will be very hard I guess).
So there is an invariant that the users can install nightly only from our extension and they can't do it manually, because when installing the nightly `.vsix` we actually save its release date to `globalState`

3577: Protect against infinite macro expansion in def collector r=edwin0cheng a=flodiebold
Something I noticed while trying to make macro expansion more resilient against errors.
There was a test for this, but it wasn't actually working because the first recursive expansion failed. (The comma...)
Even with this limit, that test (when fixed) still takes some time to pass because of the exponential growth of the expansions, so I disabled it and added a different one without growth.

3549: Implement env! macro r=matklad a=edwin0cheng
This PR implements `env!` macro by adding following things:
1. Added `additional_outdirs` settings in vscode. (naming to be bikeshed)
2. Added `ExternSourceId` which is a wrapping for SourceRootId but only used in extern sources. It is because `OUT_DIR` is not belonged to any crate and we have to access it behind an `AstDatabase`.
3. This PR does not implement the `OUT_DIR` parsing from `cargo check`. I don't have general design about this, @kiljacken could we reuse some cargo watch code for that ?
~~Block on [#3536]~~
PS: After this PR , we (kind of) completed the `include!(concat!(env!('OUT_DIR'), "foo.rs")` macro call combo. [Exodia Obliterate!](https://www.youtube.com/watch?v=RfqNH3FoGi0)

3514: vscode: askBeforeDownload option r=matklad a=Veetaha
This is a small step towards #3402, also implements my proposal stated in #3403
Also renamed `BinarySource` to `ArtifactSource` in anticipation of nightlies installation that requires downloading not a binary itself but `.vsix` package, thus generalized to `artifact` term.

The new name seems much simpler and it doesn't limit
this config value only to downloading the server binary.
Thus we wouldn't need to create another config
properties to handle other downloads whatsoever.
Anyway, I believe (heuristically) that most of the users
would want to set "askBeforeDownload": false once
and never bother clicking on the notification again
(because otherwise there is no big point in installing rust-analyzer if it cannot install the server)

3388: Remove inlay hint in diff views r=matklad a=vbfox
If the left side of a diff view that contain the old version of the file apply inlays they are misplaced and produce a weird display:

The detection is done by blacklisting the url schemes used by git and subversion scm extensions, whitelisting `file` is also possible but neither is perfect as VSCode now support both pluggable scm extensions and pluggable remote filesystems. But I suspect that the list of scm extensions is more easily manageable.
**Note**: I can rebase on #3378 if needed as it touches the same lines of code

3308: vscode: fix vscode-vim keybindings conflict r=matklad a=Veetaha
Closes#3013 I hope
vscode-vim extension overrides the `type` command so that it prevents
some keypresses to reach the text document editor.
It conflicts with our `onEnter` keybinding
that is used to support automatic doc comments extending and
indentation insertion.
The VSCode-native way to implement this would be
to use regular expressions, but as per matklad it is
considered not acceptable for the language server.
Thus we implement it via a `Enter` keybinding that
invokes our `onEnter` command which does it via the language-server.
At the end of the day we may only apply
ad hoc workarounds for conflicting extensions.
But vscode has another bug for that. You
either cannot use parantheses in `when` condition
of a keybinding or it just malfunctions.
See an issue about that here: https://github.com/microsoft/vscode/issues/91473
To get the ultimate context, follow this [zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Enhanced.20typing)

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`!

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):
