Allows creating a toolchain that's independent of the local build, for
example to make two separate toolchains with slight differences without
requiring two checkouts of clippy
changelog: none
Some developers might prefer to use alternate VCS, such as Jujutsu, which
are not detected by `cargo fix`. This forwards the `--allow-no-vcs`
command line argument to `cargo fix`.
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.
