Lintondeny(warnings),deny(deprecated),andsimilar

Denying all warnings, or even just deprecation warnings, is a forward compatibility hazard, and can also have unintended effects like masking Crater failures. I posted about this on /r/rust, and /u/Luroalive asked me to file an issue to add a clippy lint. It may actually be worth a first-class

lint in the

group, but we can consider it here first.

GitHub suggested the related issue #287 that was closed, but perhaps it's worth another look with this new context. cc
