new lints around `#[must_use]` fns `must_use_unit` lints unit-returning functions with a `#[must_use]` attribute, suggesting to remove it. `double_must_use` lints functions with a plain `#[must_use]` attribute, but which return a type which is already `#[must_use]`, so the attribute has no benefit. `must_use_candidate` is a pedantic lint that lints functions and methods that return some non-unit type that is not already `#[must_use]` and suggests to add the annotation.
