The consolidation of process_entry() and process_df_entry() allows us to
consolidate more code paths concerning rename conflicts, and to do
a few additional related cleanups. It also means we are using
rename_df_conflict_info in some cases where there is no D/F conflict;
rename it to rename_conflict_info.
