Deprecate the term "blacklist" from lints

[rpbeltran]

Many companies and open source projects have been transitioning phrases like "blacklist/whitelist" into "blocklist/allowlist" or similar. There is also precedent for this within Rust itself as in these changes in Rust Bindgen: rust-lang/rust-bindgen#1812.

With that in mind, the blacklisted_names lint seems like it could stand to be renamed to blocklisted_name. I'm not very familiar with the current strategy used for deprecation within this project, but it seems like introducing blocklisted_name as a synonym and modifying the warning messages to use this name would be a good approach for now that preserves backwards compatibility.

We had a PR for this once that went stale - #5896 . It has instructions etc.

@mikerite thanks! That's super useful. I'll use that as a reference and try to get a new PR started soon.

This seems like a reasonable change to me and would go along with changes in other repos. Most team members already stated their support in #5896, it should therefore be safe to continue with this.

@rpbeltran Could you mention the Clippy team in the PR once you created it? You can just add an cc: @rust-lang/clippy at the end of the PR description. 🙃

With that in mind, the blacklisted_names lint seems like it could stand to be renamed to blocklisted_name.

The PR @mikerite mentioned used "disallowed_names" instead, I think that's both more clear and less likely to be controversial.

I think this issue can be closed now that #8974 is merged.

Agreed. @yerke thank you for pointing that out and everyone else that participated. 🙃
