Remove dead class template (i.e. function_reference_input_iterator).

Browse Source 
Both make_function_input_iterator(function) and make...(&function)
do not depend on function_reference_input_iterator. Actually, passing a
function reference as a template argument to function_input_iterator is
not supported. Doing so results in compiler errors.
