In C++17 several classes, types and functions from functional.h are no longer available.
In this change we add first clang-tidy checks for occurrences of

- std::unary_function
- std::binary_function
- std::ptr_fun
- std::mem_fun

As there are several more deprecated types in functional.h, this check will be extended in the future.
