Check_MK Werk 5706: Windows agent: fix endianness of IP addresses

ID: 5706 Title: Windows agent: fix endianness of IP addresses Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i4 The string conversion of IP addresses was falsely done manually in network byte order, resulting in incorrect ouput for IPv6 addresses. Now the conversion is done correctly. This fix will shortly break the compatibility of logwatch state files stored by the mk_logwatch plugin of previous versions of the Windows agent as they use the remote IP address(es) of the monitoring host(s). When upgrading to the new agent, those log entries that are created exactly after stopping the old agent but before starting the new agent will be lost in monitoring. After starting the new agent, monitoring should work as before.
