Clean up the initial lambda APIs
Summary: Avoid the declaration of a secondary type variable by using a wildcard
           Predicate<P> to Predicate<? super T>
         Remove unsafe cast, casting a Predicate<? super T> to a Predicate<T>, it's not safe.
         Some Lambda constants are still declared public.
