Volker Hilsheimer 9c9c5d9828 Fix QMetaObject::invokeMethod for free functions and std::bind ... Amends 3bf5b5f894, after which free functions and std::bind could no longer be used as callables in QMetaMethod::invokeMethod. For free functions to work we need to decay to function pointers when choosing what type QtPrivate::Callable aliases. And std::bind has operator() overloads and the return type cannot be deduced. So simplify the definition of the ZeroArgFunctor - we know the function prototype if we know the return type. Add testcase for calling std::bind and free function, and remove the now unneeded helpers for functor argument and return type deduction.
