* Stricter handling of multi-namespace handling

Browse source 
* This occurs in cases where there are more than one XML namespaces in a config tree, such as `augment`:ed trees.
  * Affects all parts of the system, including datastore, backend, restconf and cli.
* Invalid api-path syntax (eg non-matching yang) error changed from 412 operation-failed to 400 Bad request invalid-value, or unknown-element.
