I changed option name from `WarnOnlyOnMultipleLocks` to `WarnOnSingleLocks`. I think for users, it will be more clear what they turn on/off. When having `WarnOnlyOnMultipleLocks` together with `WarnOnUsingAndTypedef` option, it is confusing whether first option will disable warnings on `using` and `typedef` or not. Now it is clear that options will not affect each other.
