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.
