1034: HIR diagnostics API r=matklad a=matklad
This PR introduces diagnostics API for HIR, so we can now start issuing errors and warnings! Here are requirements that this solution aims to fulfill:
* structured diagnostics: rather than immediately rendering error to string, we provide a well-typed blob of data with error-description. These data is used by IDE to provide fixes
* open set diagnostics: there's no single enum with all possible diagnostics, which hopefully should result in better modularity
The `Diagnostic` trait describes "a diagnostic", which can be downcast to a specific diagnostic kind. Diagnostics are expressed in terms of macro-expanded syntax tree: they store pointers to syntax nodes. Diagnostics are self-contained: you don't need any context, besides `db`, to fully understand the meaning of a diagnostic.
Because diagnostics are tied to the source, we can't store them in salsa. So subsystems like type-checking produce subsystem-local diagnostic (which is a closed `enum`), which is expressed in therms of subsystem IR. A separate step converts these proto-diagnostics into `Diagnostic`, by merging them with source-maps.
Note that this PR stresses type-system quite a bit: we now type-check every function in open files to compute errors!

1042: Remove windows from CI r=matklad a=matklad
We don't actually look at the CI results for windows anyway!
In general, rust-analyzer should be written in a completely
OS-independent way. That is, testing on one OS should be enough. If
this is not the case, that means something is seriously broken.
No doubt there are components which actually talk to the outside
world, and they may be platform dependent. We should extract such
components to a separate repo with an extensive multi platform CI,
like we did for VFS

1036: Assist to flip equality (==) and negated equality (!=) operands. r=matklad a=marcogroppo
This PR adds an assist to flip the equality operands.
I hope this is the right way to do this (I'm a newbie...)
Fixes#1023.

1035: Add master branch docs build and publish r=matklad a=robojumper
Closes#1024.
Additional setup required:
* The rust-analyzer travis repo needs an [environment variable](https://docs.travis-ci.com/user/environment-variables/#defining-variables-in-repository-settings) `DOCS_TOKEN` that will be used to publish docs to the `gh-pages` branch. This is a GitHub access token with the appropriate permissions to push to this repository. Travis will keep this a secret.
* In the GitHub repository settings, the GitHub pages source needs to be set to the `gh-pages` branch. This option will only appear once a branch is created with this exact name -- created either through the `deploy` step or manually.
* In the GitHub repository settings, a GitHub pages theme will need to be chosen. What theme to use is unimportant, but [you must choose a theme](https://github.community/t5/GitHub-Pages/Github-Pages-are-not-published-after-following-the-documentation/m-p/18676#M1398).
Docs are built as part of any rust build (on linux and windows, though all my Travis windows builds have timed out), but only published on master builds on linux.
The docs badge links to `https://rust-analyzer.github.io/rust-analyzer/ra_ide_api/index.html` -- since this project is a cargo workspace, there isn't a global index page, hence just the link to an arbitrarily chosen crate. If this project had a canonical main crate with good documentation, one could link to that. All other crates are accessible through the sidebar.

1031: Move most things out of ra_ide_api_light r=matklad a=detrumi
This moves everything except `structure` out of `ra_ide_api_light`. So this PR and #1019 finish up #1009, whichever is merged last should probably remove the `ra_ide_api_light` crate.
Also, `LocalEdit` was removed since it wasn't used any more.
