API tests added with this change are failing on iOS Simulator:

Tests that failed:
  LoggingTest.LOG
  LoggingTest.LOG_WITH_LEVEL
  LoggingTest.RELEASE_LOG
  LoggingTest.RELEASE_LOG_IF
  LoggingTest.RELEASE_LOG_WITH_LEVEL
  LoggingTest.RELEASE_LOG_WITH_LEVEL_IF

Actually, they fail on macOS as well:

Reverted r220938 for reason:

How is it that the so-called "early warning" bots *still* don't run API tests?

[Eric Carlson]

It looks like using pipe+fcntl+dup2 to capture stderr output doesn't work on all platforms, so maybe I should disable the tests and commit.

[Eric Carlson]

WKWebViewDoesNotLogDuringInitialization.mm uses the same technique to check for logging output, but it only fails if somethings is written to the FD so the test doesn't fail if the technique fails.
