Ed Schouten a7cb923912 Make rpc.ruserd work with utmpx/libulog.
Because strings are now null-terminated, I've decided to just use an
array of utmpx structures, instead of the separated strings. This means
we just copy the entire utmpx structure and point to the strings within
the structures directly.
