Summary: This diff is 2/3 in a sequence that introduces a skip list optimized for a key that is a freshly-allocated const char*. The change is broken into pieces to make it easier to review. This piece removes the Key template type, introduces the AllocateKey interface, and changes the unit test from using uint64_t as the Key type to using pointers to an 8 byte blob.

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 specially suitable for storing multiple terabytes of data in a single database.

The public interface is in include/. Callers should not include or

internal APIs may be changed without warning.
