This is the same situation than before, except that now, RTDM can choose
the timebase it is locked on. There is no conversion API right now, but
we could define xntbase_convert(inbase, rtdm_base), with inbase being
extracted from xnthread_timebase(xnpod_current_thread()) for primary
context services. The question remains open on how to get the inbase
pointer for seconday mode callers though.
