[PATCH 0/4] more unused-parameter fixes

Here are a few more patches to silence some -Wunused-parameter warnings. I've pulled these ones out specifically because they're a little more interesting than just "slap an UNUSED marker on the variable".

  [1/4]: mailmap: drop debugging code
  [2/4]: http: drop unused parameter from start_object_request()
  [3/4]: http: mark unused parameter in fill_active_slot() callbacks
  [4/4]: transport: mark unused parameters in fetch_refs_from_bundle()
