Known issues:
-QTBUG-36754: QBluetoothServer::close() crashes
-QTBUG-36763: QBluetothTransferManager port to Android not possible
-QTBUG-36764: Improve QBluetoothLocalDevice::connectedDevices()
-QTBUG-36810: Remove direct use of Android action strings

The above issues and some other minor TODO's will be addressed
