- Describe uvm_aobj and the lock order.
- Remove unnecessary uao_dropswap_range1() wrapper.
- KNF.  Sprinkle some __cacheline_aligned.
- Manage anonymous UVM object reference count with atomic ops.
- Fix an old bug of possible lock against oneself (uao_detach_locked() is
  called from uao_swap_off() with uao_list_lock acquired).  Also removes
  the try-lock dance in uao_swap_off(), since the lock order changes.
