  Modified files:
    sys/vm               uma_core.c
  Log:
  Better align output of "show uma" by moving from displaying the basic
  counters of allocs/frees/use for each zone to the same statistics
  shown by userspace "vmstat -z".

"The same statistics" also shows LIMIT, REQUESTS, and FAILURES.

Requests are included in the output I added, but are spelt "Requests". Limits and failures currently aren't, but adding them wouldn't be a bad idea at all. I'm also thinking off adding a "show umazone <x>" which would provide more detailed information about per-CPU caches, as we're currently looking at a potential UMA bug in a panic report on -stable. We'd pull some, but not all, of the logic from umastat.c.
