bors b239743753 Auto merge of #52644 - varkor:lib-feature-gate-2, r=withoutboats ... Add errors for unknown, stable and duplicate feature attributes - Adds an error for unknown (lang and lib) features. - Extends the lint for unnecessary feature attributes for stable features to libs features (this already exists for lang features). - Adds an error for duplicate (lang and lib) features. ```rust #![feature(fake_feature)] //~ ERROR unknown feature `fake_feature` #![feature(i128_type)] //~ WARNING the feature `i128_type` has been stable since 1.26.0 #![feature(non_exhaustive)] #![feature(non_exhaustive)] //~ ERROR duplicate `non_exhaustive` feature attribute ``` Fixes #52053, fixes #53032 and address some of the problems noted in #44232 (though not unused features). There are a few outstanding problems, that I haven't narrowed down yet: - [x] Stability attributes on macros do not seem to be taken into account. - [x] Stability attributes behind `cfg` attributes are not taken into account. - [x] There are failing incremental tests.		2018-08-06 16:58:27 +00:00
