  Add option to check state when state is unknown
  
  r341486 reverts r325483 this is a rework of the patch.
  optimize to minimize load.
  
  add option check_state_unknown to control whether a member with unknown
  device state is checked there is a small % chance that calls will be sent
  to the member when they on a call.
  
  app_queue will see a device with unknown state as available and does not 
  try verify the state without this option enabled.

CHANGES

@@ -254,6 +254,8 @@ Queue changes
  * Added member option ignorebusy this when set and ringinuse is not
    will allow per member control of multiple calls as ringinuse does for
    the Queue.
+ * Added global option check_state_unknown to enforce checking of device state
+   when the device state is unknown app_queue will see unknown as available.
