Summary: Mixing index/filter blocks with data blocks resulted in some known issues. To make sure in next release our users won't be affected, we added a new option in BlockBasedTableFactory::TableOption to conceal this functionality for now. This patch also introduced a BlockBasedTableReader::OpenOptions, which avoids the "infinite" growth of parameters in BlockBasedTableReader::Open(). Test Plan: make check Reviewers: haobo, sdong, igor, dhruba Reviewed By: igor CC: leveldb, tnovak Differential Revision: https://reviews.facebook.net/D15327
