The Great Wall of Blame
This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.

Git blame's --ignore-rev flag can be used to ignore this commit when
attempting to `git blame` some code.
