Siying Dong	e9e0101ca4	Move test related files under util/ to test_util/ (#5377) ... Summary: There are too many types of files under util/. Some test related files don't belong to there or just are just loosely related. Mo ve them to a new directory test_util/, so that util/ is cleaner.

Andrew Kryczka	a720401877	Avoid acquiring SyncPoint mutex when it is disabled (#3991) ... Summary: In `db_stress` profile the vast majority of CPU time is spent acquiring the `SyncPoint` mutex. I mistakenly assumed #3939 had fixed this mutex contention problem by disabling `SyncPoint` processing. But actually the lock was still being acquired just to check whether processing is enabled. We can avoid that overhead by using an atomic to track whether it's enabled.
