  SVN rev 220602 on 2011-04-13 16:20:54Z by mav
  
  Improve SATA Asynchronous Notification feature support in CAM:
   - make SATA SIMs announce capabilities to handle SDB with Notification bit;
   - make PMP driver honor this SIMs capability;
   - make SATA XPT to negotiate and enable this feature for ATAPI devices.
  
  This feature allows supporting SATA ATAPI devices to inform system about
  some events happened, that may require attention. In my case this allows
  LG GH22LS50 SATA DVR-RW drive to report tray open/close events. Events
  reported to CAM in form of AC_SCSI_AEN async. Further they could be used
  as a hints for checking device status and reporting media change to upper
  layers, for example, via spoiling mechanism of GEOM.
