      Bug#15959313 CONVERT EXISTING UNIT TESTS FROM TAP TO GOOGLETEST
      
      Mostly simple rewrite:
      ok(predicate, message) ==> EXPECT_TRUE(predicate) << message;
      
      Remove main() functions, and add TEST(X,Y) instead.
     @ include/my_atomic.h
        declare my_atomic_initialized as extern "C"
     @ unittest/gunit/bounded_queue-t.cc
        Reduce test execution time.

    removed:
