Description

We were using postfixes to avoid inference problems around operator methods (such as fromIterable vs fromArray) but there is at least one operator currently, startWith, that may exhibit type ambiguity. A dedicated postfixed name should resolve the issue, such as:

1. startWith(T) + startWithIterable(Iterable<T>)
2. startWithItem(T) + startWith(Iterable<T>) + remove startWith(T)
3. startWithItem(T) + startWithIterable(Iterable<T>) + remove startWith(T).

As a preparation, we can deprecate startWith(T) within 2.2.x in case option 2 or 3 is chosen.
