New Lint: `wildcard imports` Fixes rust-lang#1228 ### A few notes: - I put this lint in the pedantic group, even though in the issue restriction was mentioned. - Every fallout fix was automatically applied by `cargo fix` (This produced 3 `unused_imports` warnings) and are in commit 7e834c8. So reverting these changes wouldn't be a problem. ### A few ideas: - A configuration to specify the amount of imported Items, where a `*` might be better. - ~~A configuration to disable the lint for enums. Or just disable the lint for enums, since there is [`enum_glob_use`](https://rust-lang.github.io/rust-clippy/master/index.html#enum_glob_use)~~ I moved `enum_glob_use` into this lint in 12937f0 ### A few quotes from the issue: > Is there a way to ask the compiler about the modules or symbols that the current file is using? Yes there is. I found it, once I was nearly finished implementing it myself. See 321d64a > one hard optional feature would be to figure out what is currently used and add a suggestion to replace it with a full import list. Yeah that was pretty hard, until I found the query for this. Queries are cool, but too hard to find. > FWIW VS Code and Intellij IDEA both offer imports deglobbing which replace * with required imports. And now, Clippy can do this too! 🎉 --- Your thoughts on the notes/ideas? changelog: Add new lint [`wildcard imports`]. Add suggestion to [`enum_glob_use`]
