Prevent nullPointerException by updateBondedBluetoothDevices

In some very rare cases difficult to identify, it seems that the
IBluetooth.getBondedDevices() returns a Set with a null element.

This patch will prevent calling getBondState() if the device is null to
avoid a nullPointerException.

XmlUtils#readThisMapXml should handle null keys.

Both readThisValueXml & writeThisValueXml have been
implemented to handle values with "null" names.

Change readThisMapXml to allow such names as well, and
map them to the null key in the resulting HashMap.
readThisListXml and readThisSetXml already support
null names.
