sdong e0a87c4cf1 DBIter to use static allocated char array for saved_key_ (if it is not too long) 
Summary: DBIter now uses a std::string for saved_key. Based on some profiling, it could be more expensive than we though. Optimize it with the same technique as LookupKey -- if it is short, we copy it to a static allocated char. Otherwise, dynamically allocate memory for it.

Test Plan: make all check
