Merge the 1.8.x-r1537193/ branch:

 * r1537193, r1537221, r1540428
   Add test to verify if the used ZLib is affected by some block size bugs that
   affect our usage of serf.
   Justification:
     Most Windows binaries were affected by this bug and we should verify
     that we don't accidentally reintroduce this problem.
   Notes:
     This patch needs the source directory for obtaining its test data. The
     backport branch contains portions of r1537147 and r1537190 to enable
     this test.
