* Add multiple yang support also for obsolete versions

Browse source 
* This means that files and datastores supporting modstate also looks for deleted or updated yang modules.
  * A stricter binding which gives error if loading outdated YANG file does not exist.
* Stricter yang checks: you cannot do get-config on datastores that have obsolete YANG
* Added xerr output parameter to `xmldb_get0()`
