- pessimizing move in wallet2 prevents copy ellision - various for loops were creating copies (clang-10 now warns about this). Mostly this is because they had the type wrong when looping through a map: the iterator type of a `map<K, V>` is `pair<const K, V>` not `pair<K, V>`. Replaced them with C++17: for (const auto& [key, val] : var) which is so much nicer. - cryptonote::core did not have a virtual destructor, but had virtual methods (causing both a warning, and likely a crash if we ever have something inheriting from it held in a unique_ptr<core>). - core() constructor still had explicit even though it lost the single argument. - test code class had a `final` destructor but wasn't marked final. (It also has a billion superfluous `virtual` declarations but I left them in place because it's just test code).
