diff: mark unused parameters in callbacks
The diff code provides a format_callback interface, but not every callback needs each parameter (e.g., the "opt" and "data" parameters are frequently left unused). Likewise for the output_prefix callback, the low-level change/add_remove interfaces, the callbacks used by xdi_diff(), etc. Mark unused arguments in the callback implementations to quiet -Wunused-parameter.
