lint: remove or comment out unused functions

Cppcheck has identified a lot of unused functions. This removes funcs that
are unlikely to ever be used. Others that might be useful for debugging I've
commented out with "#if 0".

A better approach would be some profile object that all contexts share, and that tracks the eval levels on its own. */
