hg: lambda/lambda/jdk: - remove Spliterator.iterator(), see Streams.iteratorFrom for equivalent

[Brian Goetz]

Doug and I have been working on the form for Spliterator.  We've combined the advance/get methods into tryAdvance, which sends the next element (if present) to the provided Block.  So there is:

  trySplit -> return spliterator or null
  tryAdvance(Block) -> send element to Block if present; return whether there was an element
  forEach(Block) -> send remaning elements to Block
