receive-pack, fetch-pack: reject bogus pack that records objects twicejc/index-pack-reject-dups
When receive-pack & fetch-pack are run and store the pack obtained over
the wire to a local repository, they internally run the index-pack command
with the --strict option. Make sure that we reject incoming packfile that
records objects twice to avoid spreading such a damage.
