This enables the same warnings that are enabled in `clippy_lints` also
in `clippy_utils` and `clippy_dev`. Then it makes sure, that the
`deny-warnings` feature is passed down to `clippy_lints` and
`clippy_utils` when compiling Clippy.
Great for spotting false positives/broken suggestions of applicable lints.
There are false positives though becasue I'm not sure yet how to silence rustc warnings while keeping clippy warnings.
Sometimes rustc makes a suggestion that fails to apply and the implementation does not differenciate between clippy and rustc warnings when applying lint suggestions.
changelog: none
This takes an absolute path to a rustc repo and adds path-dependencies
that point towards the respective rustc subcrates into the Cargo.tomls of
the clippy and clippy_lints crate.
This allows rustc-analyzer to show proper type annotations etc on rustc-internals inside the clippy repo.
Usage: cargo dev ra-setup /absolute/path/to/rust/

If you've been using `./util/dev` before, this now becomes `cargo dev`.
The key part of this change is found in `.cargo/config`.
This means one less shell script and a bit more cross-platform support
for contributors.
This adds a check to `clippy_dev` that enforces a maximum line count for
`stderr` files. CI will fail if the line count is exceeded. It's
currently set to `320` lines.
Ideally this would be implemented in `compiletest-rs` but there are
plans to move Rust's `compiletest` into the `compiletest-rs` repository
and I don't want to do the work in `compiletest` twice. However, I also
don't want to wait until the move is done, so I added the check to
`clippy_dev` until it makes sense to add it to compiletest-rs.
