Summary: (1) Fix SanitizeOptions() to also check HashLinkList. The current dynamic case just happens to work because the 2 classes have the same layout. (2) Do not delete SliceTransform object in HashSkipListFactory and HashLinkListFactory destructor. Reason: SanitizeOptions() enforces prefix_extractor and SliceTransform to be the same object when Hash**Factory is used. This makes the behavior strange: when Hash**Factory is used, prefix_extractor will be released by RocksDB. If other memtable factory is used, prefix_extractor should be released by user. Test Plan: db_bench && make asan_check Reviewers: haobo, igor, sdong Reviewed By: igor CC: leveldb, dhruba Differential Revision: https://reviews.facebook.net/D16587
