The rocksdb team removed the long-standing "raw pointer" rocksdb::DB::Open() API in favor of the unique_ptr version. The reason we were using the raw pointer version is because it was more compatible with older versions, including the one that ships with Fulcrum. As a result we were forced to create a "Compat" later in Storage/ for rocksdb::DB::Open that smoothes over the differences. This commit just makes all calls to rocksdb::DB::Open() in the codebase go through Compat::DBOpen.
