If a scsi_device supports async notification for media change, then
let user space know this capability exists by creating a new sysfs
entry "media_change_notify", which will be 1 if it is supported, and
0 if not supported.  Create a routine which allows scsi devices to
send a uevent when media change events occur.

if James is happy with this patch, I'm happy with patch #2 and #3

Actually, we just got a second potential consumer ... although I'll
reprod to have the reporter send it to the list.  It's a device that
needs notice of report luns data changing.  The proposed mechanism looks
a bit narrow now (too tied to media change).  I'll see if I can propose
a more generic update.

Too narrow because it's tied to scsi_device?  Obviously it'd be easy
to expand the scsi_device_event enum to include LUNS_DATA_CHANGE or 
something, and even the scsi_device_event_info struct can easily be 
expanded if you need more info attached to the event.  Let me know if 
there's something specific I can help with.
