* xml_merge() changed to use 3-value return: 1:OK, 0:Yang failed, -1: Error

Browse source 
* `clixon_netconf_error(category, xerr, msg, arg)` removed first argument -> `clixon_netconf_error(xerr, msg, arg)`
* Renamed utility function `clixon_util_insert()` to `clixon_util_xml_mod()` and added merge functionality.
* Fixed: Insertion of subtree leaf nodes were not made in the crrect place, always ended up last regardless of yang spec (if ordered-by system).
