Summary: Greatly reduced the not-quite-copy-paste giant parameter lists of rocksdb::NewTableBuilder, rocksdb::BuildTable, BlockBasedTableBuilder::Rep ctor, and BlockBasedTableBuilder ctor. Moved weird separate parameter `uint32_t column_family_id` of TableFactory::NewTableBuilder into TableBuilderOptions. Re-ordered parameters to TableBuilderOptions ctor, so that `uint64_t target_file_size` is not randomly placed between uint64_t timestamps (was easy to mix up). Replaced a couple of fields of BlockBasedTableBuilder::Rep with a FilterBuildingContext. The motivation for this change is making it easier to pass along more data into new fields in FilterBuildingContext (follow-up PR).

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.
