Summary: BlockBasedTableBuilder uses ExtractUserKey in EnterUnbuffered. This would cause index filter building error, since user-provided timestamp is supported by ExtractUserKeyAndStripTimestamp, and it's used in Add. This commit changes ExtractUserKey to ExtractUserKeyAndStripTimestamp. A test case is also added by modifying DBBasicTestWithTimestampWithParam_ PutAndGet test in db_basic_test to cover ExtractUserKeyAndStripTimestamp usage in both kBuffered and kUnbuffered state of BlockBasedTableBuilder. Before the ExtractUserKeyAndStripTimstamp fix: ``` $ ./db_basic_test --gtest_filter="*PutAndGet*" Note: Google Test filter = *PutAndGet* [==========] Running 2 tests from 1 test case.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
