I think I thought then that kvm_uread() was for internal usage only
(it was used by libkvm only for reading process args and env via
procfs(5), no other consumers were found in base, no man page). Also
reading from procfs(5) did not look like libkvm job, so after the last
consumers had been removed, retiring it looked natural. I think I
overlooked the declaration in kvm.h and that I might break ABI,
otherwise it would have made me think more and ask other people if the
removal was ok.

Suggestions how this should be fixed properly (if possible) are highly
appreciated. I will do what people suggest.
