Tighten the restrictions of the linter

This change causes the linter to be a bit more complainy. The hope is
that this will cut down on some of the more pedantic issues being caught
in code reviews, and thus reduce the overall time a change spends in the
review process.

This change includes various changes to the codebase to bring it up to
the new standards.
