memory leak in get API

[heidawei]

we need free slice after get from rocksdb, and copy data before return ????

appears so, I was getting data corruption on my Get calls and had to add a copy. Seems to have solved the corruption issue

result, err := db.Get(ro, key)
	if err != nil {
		result.Free()
		panic(err.Error())
	}
	tmpData := make([]byte, len(result.Data()))
	copy(tmpData, result.Data())
	defer result.Free()
        return tmpData

What about using GetBytes?

@jiminoc This free() bothered me for a few days, but it worked. Otherwise, memory will grow dramatically
