* Backport from upstream (with corrections, sent upstream):
  - Defer the fsync and rename for normal files in tar extraction so that
    it's done in one pass afterwards, to avoid massive I/O degradation due
    to the serialization from each write + fsync. This restores extraction
    times to numbers closer to the ones before the fsync patch introduced
    in 1.15.6.
