Title: Implement lint plugins

This is a rebase of #14804 with two new commits on top to implement and test lint plugins.

r? @alexcrichton @huonw: Can you take a look at the new commits, and also weigh in about any issues from the old PR that you feel are still unresolved? I'm leaving the old branch alone to preserve discussion history.
