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.
This template-ifies Router::NotifyRouterEvent() up so that it accepts
the arguments to instantiate the specified event type, forwarding them
to std::make_unique. This would allow (in the future) the function to
no-op the call and avoid memory allocation. It also slightly reduces
the amount of code required to fire an event.
This commit also simplifies some of the RouterEvent code to reduce
redundancy.
