Bug 906020: Implement non-blocking BluetoothArrayOfDevicePropertiesRunnable, r=echou,gyeh

BluetoothArrayOfDevicePropertiesRunnable used to block while waiting
for the results of the 'GetProperties' messages it sends over DBus. With
this patch, each 'GetProperties' operation is performed asyncronously
and the result is handled in a DBus reply handler. The same reply handler
gets used for all 'GetProperties' messages until all devices have been
processed. In this case the final Bluetooth reply runnable gets
dispatched.

The old function GetPropertiesInternal is now unused and has been
removed.

With the completely non-blocking handling of 'GetProperties' message
there is no need for BluetoothArrayOfDevicePropertiesRunnable any longer.
