The ntp_gettime implementation of NTP exports the tai field the kernel now produces. This requires an ABI change since the ntptimeval structure changed. Upstream kept the same name, there is nothing to do. This patch changes the ntptimeval structure but keeps the old ntp_gettime definition. A new ntp_gettimex function which is transparently invoked through the old name is introduced. This has the advantage that even object files can remain compatible. This wouldn't be the case if symbol versioning would be used to overload the name ntp_gettime.
