1148: Add token_tree_to_xxx functions r=matklad a=edwin0cheng
<del>As discus in PR #1147 , this PR added a `mbe::MacroKind` .
Currently only 2 kind of macro are supported, `SourceFile` and `Block`.</del>
Added following functions for `tt::TokenTree` and `ast::Node` conversion:
* token_tree_to_expr
* token_tree_to_pat
* token_tree_to_ty
* token_tree_to_macro_stmts
* token_tree_to_macro_items
And added two new syntax kind:
* MACRO_ITEMS
* MACRO_STMTS

1145: Fix#1099, plug self type type parameters in infer_path_expr r=flodiebold a=edwin0cheng
As discussed in #1099, this PR try to "plug" a `self type` type parameters in `infer_path_expr`.
All the cases in 1099 was fixed and tested.
And luckily, this PR fixed bug #1030 again and make the test output correct.

1153: "Restart server" command r=jrvidal a=jrvidal
The only tricky aspect is that fact that once the `exit` command has been received, we no longer need to join on the reader thread.
Also, I think `terminateProcesses.sh` was not working properly. In fact, the very same script from the vscode language server implementation is not working either! It's because of that I noticed the reader thread issue 😮

This fixes the order in which candidates are chosen a bit (not completely
though, as the ignored test demonstrates), and makes autoderef work with trait
methods. As a side effect, this also makes completion of trait methods work :)
1137: Adds support for multiple editor workspaces on initialization r=matklad a=jrvidal
OK, so this "simple hack" turned out to be way more contrived than I expected 😂
### What works
This patch only handles multi-folder editor workspaces _on initialization_.
* I've found that modifying the layout of a workspace in VSCode just reloads the extension, so this hack should be enough for now.
* Not sure about how emacs-lsp behaves, but we fallback gracefully to the mono-folder workspace, so it should be fine.
### What doesn't work
* [x] `cargo watch` can only watch a single root folder with a `Cargo.toml`. I've left this part untouched but we could either warn that it's not supported or launch _multiple_ `cargo-watch` processes.
* [x] The `rust-analyzer/runnables` command is not functional, since we don't send the correct `cwd`.
* [x] Should we add some happy path test to `heavy_tests`?
* [ ] Going from a single `root` to multiple `roots` leaves us with a couple of `n * m` loops that smell a bit. The number of folders in the editor workspace is probably low though.

1138: Add L_DOLLAR and R_DOLLAR r=matklad a=edwin0cheng
As discussion in issue https://github.com/rust-analyzer/rust-analyzer/issues/1132 and PR #1125 , this PR add 2 `Syntax::Kind` : `L_DOLLAR` and `R_DOLLAR` for representing `Delimiter::None` in mbe and proc_marco. By design, It should not affect the final syntax tree, and will be discard in `TreeSink`.
My original idea is handling these 2 tokens case by case, but i found that they will appear in every place in the parser (imagine `tt` matcher). So this PR only handle it in `Parser::do_bump` and `Parser::start`, although It will not fix the `expr` matcher executing order problem in original idea.

- make it possible to get parent trait from method
- add 'obligation' machinery for checking that a type implements a
trait (and inferring facts about type variables from that)
- handle type parameters of traits (to a certain degree)
- improve the hacky implements check to cover enough cases to exercise the
handling of traits with type parameters
- basic canonicalization (will probably also be done by Chalk)
