1175: Fix bugs and add error log about macro expansion r=matklad a=edwin0cheng
This PR fixed / add following things:
* Add a fused count which stop recursion of macro expansion in name resolution.
* Add some logs when macro expansion fails
* Add `$crate` meta variable support in mbe, which create a `$crate` ident token in token tree.
* Fixed matching a `$REPEAT` pattern inside a subtree, e.g. `(fn $name:ident {$($i:ident)*} ) => {...}`
* Remove composite-able punct token in syntax node to token conversion.

1154: Initial support for lang items (and str completion) r=flodiebold a=marcogroppo
This PR adds partial support for lang items.
For now, the only supported lang items are the ones that target an impl block.
Lang items are now resolved during type inference - this means that `str` completion now works.
Fixes#1139.
(thanks Florian Diebold for the help!)

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 :)
