[v6r12 or v6r13] Removed old RMS

This PR removes the old RMS from the system. 

This PR can go for v6r12 or v6r13, but it has to be said that the old RMS would, most probably, not work even now: the few dependencies between the old RMS and the new one are not maintained any more, and actually it seems that no one cares about maintaining it. So, my suggestion would be to simply merge this one in v6r12 and announce that the old RMS is dead and should be removed before installing v6r12.
