sdong 28b5c76004 WriteBatchWithIndex: a wrapper of WriteBatch, with a searchable index ... Summary: Add WriteBatchWithIndex so that a user can query data out of a WriteBatch, to support MongoDB's read-its-own-write. WriteBatchWithIndex uses a skiplist to store the binary index. The index stores the offset of the entry in the write batch. When searching for a key, the key for the entry is read by read the entry from the write batch from the offset. Define a new iterator class for querying data out of WriteBatchWithIndex. A user can create an iterator of the write batch for one column family, seek to a key and keep calling Next() to see next entries. I will add more unit tests if people are OK about this API. Test Plan: make all check Add unit tests.
