move toStdFunction() to pibase.h refactor PIParseHelper, now it much more abstract and useful fix PIIODevice::createFromFullPath() when whitespaces at start or end are presence PIStreamPacker add events for start and end packet receive PIClientServer::ClientBase add virtual methods for start and end packet receive. also one can enable diagnostics with enableDiagnostics() method PICout now call flush() on each end of output add PIString::entries(const PIString & str)
