ucounts: Split rlimit and ucount values and max values

After the ucount rlimit code was merged a bunch of small but
siginificant bugs were found and fixed.  At the time it was realized
that part of the problem was that while the ucount rlimits were very
similar to the oridinary ucounts (in being nested counts with limits)
the semantics were slightly different and the code would be less error
prone if there was less sharing.  This is the long awaited cleanup
that should hopefully keep things more comprehensible and less error
prone for whoever needs to touch that code next.
