Currently this only provides the feature to auto-update the versions in the
`Cargo.toml` files. With the move to Josh, a command to get beta and stable
release commits will be added.
Currently this only provides the feature to auto-update the nightly version in
the `rust-toolchain` file and the `clippy_utils/README.md` file. The actual sync
to and from the Rust repo will be added with the move to Josh.
There was some dependence between the different subcommands of clippy_dev. And
this dependence will increased with the introduction of the sync and release
subcommands. This moves the common functions to a `utils` module, to decouple
the other modules.
Now that lints can add @eval_always at the end of their definition, the lint
declaration might not end right after the description. The `update_lints`
command can skip everything that comes after that.
Rewrite lints page
This PR has multiple goals:
* Make lints page to work without needing a web server by removing the json file.
* Prepare the field to also make the page work with JS (not done in this PR but should be straightforward).
* Remove angular dependency.

Add lint for `unused_result_ok`
This PR adds a lint to capture the use of `expr.ok();` when the result is not _really_ used.
This could be interpreted as the result being checked (like it is with `unwrap()` or `expect`) but
it actually only ignores the result.
`let _ = expr;` expresses that intent better.
This was also mentionned in #8994 (although not being the main topic of that issue).
changelog: [`misleading_use_of_ok`]: Add new lint to capture `.ok();` when the result is not _really_ used.
* Construct lint passes by taking `Conf` by reference.
* Use `HashSet` configs in less places
* Move some `check_crate` code into the pass constructor when possible.
The `restriction` group contains many lints which are not about
necessarily “bad” things, but style choices — perhaps even style choices
which contradict conventional Rust style — or are otherwise very
situational. This results in silly wording like “Why is this bad?
It isn't, but ...”, which I’ve seen confuse a newcomer at least once.
To improve this situation, this commit replaces the “Why is this bad?”
section heading with “Why restrict this?”, for most, but not all,
restriction lints. I left alone the ones whose placement in the
restriction group is more incidental.
In order to make this make sense, I had to remove the “It isn't, but”
texts from the contents of the sections. Sometimes further changes
were needed, or there were obvious fixes to make, and I went ahead
and made those changes without attempting to split them into another
commit, even though many of them are not strictly necessary for the
“Why restrict this?” project.
