John Baldwin 6426978617 Extend the VMM stats interface to support a dynamic count of statistics.
- Add a starting index to 'struct vmstats' and change the
  VM_STATS ioctl to fetch the 64 stats starting at that index.
  A compat shim for <= 13 continues to fetch only the first 64
  stats.

- Extend vm_get_stats() in libvmmapi to use a loop and a static
  thread local buffer which grows to hold the stats needed.
