* PIThread::~PIThread() now unregister itself from introspection, if terminates than show warning * PISystemMonitor now correctly stops * PIPeer now can correctly stopAndWait * PIPeer::destroy(), protected method for close all eths and threads * new PIINTROSPECTION_STOP macro * Introspection now can be correctly stopped by macro, more safety ClientServer: * ClientBase::close() stop and disconnect channel * Server clients clean-up now event-based * No warnings on client destructor
