tag: mark unused parameters in each_tag_name_fn callbacks

We iterate over the set of input tag names using callbacks. But not all
operations need the same inputs, so some parameters go unused (but of
course not the same ones for each operation). Mark the unused ones to
avoid -Wunused-parameter warnings.
