Replace _call_exc_callbacks with a function wrapper, which will automatically call exception callbacks when an exception is raised from the function. This removes the need to specify the function and its arguments twice (once in the function call itself and once in _call_exc_callbacks). Add some extra checks to existing exception callbacks.
