900: Add new trait ast::TypeAscriptionOwner r=vipentti a=vipentti
This trait should be implemented for nodes which have an ascribed type,
e.g. thing : Type. Such as let, const, static, param, named struct fields.
In addition, we update some places where previously we used node + node.type_ref() with `TypeAscriptionOwner` in the trait bounds.

901: Add basic support for showing fn signature when hovering r=matklad a=vipentti
This adds basic support for displaying function signature when hovering over a usage of a function.
Additionally refactored `hover` to return `HoverResult` to ease with testing and in general to be more robust.

903: Work around for issue in vscode reporting a failure in request r=matklad a=vipentti
vscode would report "A request has failed" when it got "Content modified"
message and this would cause a pop-up to appear. This works around the issue by
returning an "empty" response that vscode can ignore.

This replaces places where we would use node + node.type_ref() with things that
have an ascribed type, with using the TypeAscriptionOwner as the trait bound so
we can simply pass the node.
899: Change default value of highlightingOn to false r=matklad a=vipentti
This changes the default value for the vscode setting `rust-analyzer.highlightingOn` to `false`. Since currently the highlighting only supports Zenburn, which people may not be using, I think it makes sense to have this feature disabled by default.
This was discussed in #896

897: Add basic const/static type inference r=flodiebold a=vipentti
This adds basic const/static type inference discussed in #887.
Currently the inference does not work for const/static declared inside a block. In addition the inference does not work inside the bodies of const/static.

892: Type aliases r=matklad a=flodiebold
This implements type aliases (i.e. `type` definitions).
There's just one snag: handling recursion. E.g. `type Foo = Foo` makes type inference panic with a query cycle. I think the best way to handle this would be if Salsa provided the ability to catch cycle errors? It seems that there's some work underway to support this [here](https://github.com/salsa-rs/salsa/issues/6) and [here](https://github.com/salsa-rs/salsa/pull/147). Should we wait for this? I don't see a good way to handle this without help from Salsa.
