Fwd: hg: lambda/lambda/jdk: Add .unordered() operation; eliminate .collectUnordered()

[Brian Goetz]

Stream.collectUnordered has been removed in favor of a more general 
.unordered() method (which may be a no-op if the stream is already 
unordered.)  This allows more stateful and terminal ops to gain the 
benefit of opting out of ordering.

The collect(Collector) method currently performs a concurrent collection 
when all of the following are true:
  - the stream is parallel
  - the collector is concurrent
  - the collector is unordered OR the stream is unordered

Currently the groupingByConcurrent / toConcurrentMap collectors are not 
UNORDERED.  Meaning that users still have to have an unordered source 
(or ask for unordered explicitly) to get concurrent collection.  I'm 
currently working through what it would look like if this were reversed, 
and these collectors declared UNORDERED.
