Subject: [PATCH] sync with upstream @21627589

Minor changes:
* Reformat the bodies of the iterator interface routines in IteratorWrapper to
  make them a bit easier to read
* Switched the default in the leveldb makefile to be optimized mode, rather
  than debug mode
* Fix build problem in chromium port
