  Log:
  Introduce an MI cpu synchronization API, redo the SMP AP startup code,
  and start cleaning up deprecated IPI and clock code.  Add a MMU/TLB page
  table invalidation API (pmap_inval.c) which properly synchronizes page
  table changes with other cpus in SMP environments.
  
      * removed (unused) gd_cpu_lockid
      * remove confusing invltlb() and friends, normalize use of cpu_invltlb()
        and smp_invltlb().
      * redo the SMP AP startup code to make the system work better in
        situations where all APs do not startup.
      * add memory barrier API, cpu_mb1() and cpu_mb2().
      * remove (obsolete, no longer used) old IPI hard and stat clock forwarding
        code.
      * add a cpu synchronization API which is capable of handling multiple
        simultanious requests without deadlocking or livelocking.
      * major changes to the PMAP code to use the new invalidation API.
      * remove (unused) all_procs_ipi() and self_ipi().
      * only use all_but_self_ipi() if it is known that all AP's started up,
        otherwise use a mask.
      * remove (obsolete, no longer usde) BETTER_CLOCK code
      * remove (obsolete, no longer used) Xcpucheckstate IPI code
