  Log:
  Give this code a major facelift:
  
   - replace the simplelock in struct vm_zone with a mutex.
  
   - use a proper SLIST rather than a hand-rolled job for the zone list.
  
   - add a subsystem lock that protects the zone list and the statistics
     counters.
  
   - merge _zalloc() into zalloc() and _zfree() into zfree(), and
     move them below _zget() so there's no need for a prototype.
  
   - add two initialization functions: one which initializes the
     subsystem mutex and the zone list, and one that currently doesn't
     do anything.
  
   - zap zerror(); use KASSERTs instead.
  
   - dike out half of sysctl_vm_zone(), which was mostly trying to do
     manually what the snprintf() call could do better.
