refactor(non-src): apply pedantic lints (#976)
Fixes many not yet enabled lints (mostly pedantic) on everything that is
not the lib (examples, benchs, tests). Therefore, this is not containing
anything that can be a breaking change.

Lints are not enabled as that should be the job of #974. I created this
as a separate PR as its mostly independent and would only clutter up the
diff of #974 even more.
