#2264: Add stricter warnings for apps that use them #2282

Merged

nlslatt merged 21 commits into develop from 2264-enable-more-warnings

Enable more warnings when building the project.

The most common warning here is unused variable / parameter. Silencing it with [[maybe_unused]] attribute is explicit and reasonably concise, so I'm going with that in most cases (b832ffc handles cases unsupported in gcc-8).

fixes #2264

Looking ahead, you may want to explicitly add warnings about performance-impacting things -Wredundant-move, -Wpessimizing-move, and -Wrange-loop-construct, separate from their current default inclusion in GCC's -Wall
