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.
