Remove warnings that appear even in debug build

Registered by jeroenp

Currently there are 26 warnings in the debug build (so this is not about missing or wrong XML comments), most of which are due to non-used parameters or unreachable code. My guess would be that most of these warnings are there due to left-over debug-code. As a result new warnings are not noticed anymore. Cleaning up should make warnings again something people fix when they create one.
