Auto merge of #5109 - phansch:ciao_util_dev, r=flip1995
Deprecate util/dev in favor of cargo alias This means one less shell script and a bit more cross-platform support for contributors. If you've been using `./util/dev` before, this now becomes `cargo dev`. The key part of this change is found in `.cargo/config` where an alias for calling the `clippy_dev` binary is defined. changelog: none

The [`plugin::PluginRegistry`][plugin_registry] provides two methods to register lints: [register_early_lint_pass][reg_early_lint_pass] and [register_late_lint_pass][reg_late_lint_pass].
|
||||
Both take an object that implements an [`EarlyLintPass`][early_lint_pass] or [`LateLintPass`][late_lint_pass] respectively. This is done in every single lint.

It's worth noting that the majority of `clippy_lints/src/lib.rs` is autogenerated by `util/dev update_lints` and you don't have to add anything by hand. When you are writing your own lint, you can use that script to save you some time.
