Norman Feske 76ecfff7b6 os: Handle corner case in Xml_node::sub_node
When calling 'sub_node' on a node with no sub nodes, the Xml_node would
interpret the characters after the current node while searching for sub
nodes. The patch adds a sanity check that lets the 'sub_node' function
throw an exception when called on a node with no sub nodes.
