[PATCH 06/17] commit-graph: extract fill_oids_from_packs()




From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>

The write_commit_graph() method is too complex, so we are
extracting methods one by one.

This extracts fill_oids_from_packs() that reads the given
pack-file list and fills the oid list in the context.
