  Allow capturing process stdout and stderr interleaved
  
  The test utils are enhanced to allow redirecting stderr to stdout.  This
  is in preparation for a change that makes the test runner capture stderr
  together with stdout.  Currently, on failure logs originating from
  UNIMPLEMENTED() and other such macros are not captured.
