Negative size buffers detection. In the past, there were several security issues which resulted in worker process memory disclosure due to buffers with negative size. It looks reasonable to check for such buffers in various places, much like we already check for zero size buffers. While here, removed "#if 1 / #endif" around zero size buffer checks. It looks highly unlikely that we'll disable these checks anytime soon.
