- RlinkCommand,RlinkCommandList: add move version of methods - use constructor delegation - use nullptr - drop empty destructors for pod-only classes - RlinkCommand: rename IsBlockExt -> HasBlockExt - RlinkConnect: add BadPort(); used on all hard port checks - remove contraproductive moves (-Wpessimizing-move) - add casts (-Wfloat-conversion, -Wdouble-promotion) - virtual dtor now outlined to streamline vtable - make Dump non virtual in some cases (-Wnon-virtual-dtor) - rename variables in shadow situations (-Wshadow)
