    lapic timer: Finish the lapic timer support
    
    - Add lapic_timer_process_oncpu(), which fires per-cpu systimer queue.
    - Add lapic_timer_intr_reload(), which restart/start lapic timer.
    - Change cputimer_intr_reload to function pointer, so it could be
      overridden when needed.  It is original cputimer_intr_reload function
      on amd64 and vkernel.  On i386, APIC initialization will set it to
      lapic_timer_intr_reload if lapic_timer_enable tunable is set to 1,
      else i8254_intr_reload (origial cputimer_intr_reload) will be used.
    - If lapic_timer_enable is 1, then don't try to register "clk" interrupt
      handler at all.
    
    As of this commit, lapic timer support is done.  It is not enabled by
    default, set 'hw.lapci_timer_enable' to enable it.
