This is working, but I'm not that happy with how the lowering works. We might
need an additional representation between `TypeRef` and `Ty` where names are
resolved and `impl Trait` bounds are separated out, but things like inference
variables don't exist and `impl Trait` is always represented the same
way.
Also note that this doesn't implement correct handling of RPIT *inside* the
function (which involves turning the `impl Trait`s into variables and creating
obligations for them). That intermediate representation might help there as
well.

4739: Declare required lsp-server dependency of rust-analyzer crate r=jonas-schievink a=dtolnay
My codebase already depended on lsp-server and introducing a dependency on rust-analyzer failed at first because it assumes some functions that were first present in lsp-server 0.3.2.

4660: Enable hover and autocomplete docs on macro generated items r=aloucks a=aloucks
Enable hover and autocomplete docs on macro generated items. This de-sugars doc comments into `doc` attributes in some cases, but not all. Comments and `doc` attributes are then merged together.
This PR is essentially a partial implementation of what's being suggested #3182, but it's not all the way there yet. ~I still need to add unit tests~, but I wanted to first get feedback on whether or not this was an acceptable path forward.

Removes the duplicated `expand_doc_attrs` and `merge_doc_comments_and_attrs`
functions from `ra_ide` and exposes the same functionality via
`ra_hir::Documentation::from_ast`.
Eventually, we should support "just open random rust file" use case,
we don't really do this now, so let's avoid spending time on it until
we fix it properly.
4721: Hide squiggly for unused and unnecessary diagnostics r=matklad a=GabbeV
Fixes#4229
When working with JavaScript or TypeScript in VSCode unused valiables are faded but don't have a squiggle. This PR makes rust-analyzer work similarly by setting the severity to hint when applying the unnecessary tag.
VSCode usually shows a squiggle for error, warning and information and shows three dots for hint. When the unnecessary tag is present the squiggles will still show up but the three dots will not.
This is my first contribution to open source. Please tell me if i need to do anything more to get this PR considered.
