DA/DU changes

[Brian Goetz]

The likelihood is that the adjustments to DA/DU will also apply to inner classes as well. We are evaluating each of the "differences" between lambdas and inner classes, and for each will have to make a decision on which to make "consistent", and there are some that we will definitely not be able to port back (such as the scoping rules for names).  Note that "it seems inconsistent" is something that will be true about Java always, no matter what we do.  But we can try to pick the inconsistencies that make the least un-sense.
