Previously we did not call onDetached on old native AwContents, which now no longer cleans up hardware resources correctly. This also had the side effect that the following onAttach with the new native AwContents is ignored in java code due to attach/detach mismatch. As make onDetached more strict with respect to ordering. And lock to protect variable accessed on multiple threads. Also need to ensure we never requestDrawGL on the blank native AwContents that's destroyed during pop up.
