important:

* 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
