* 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).

* Utility for manipulating XML trees. In all operations, there is a primary base tree x0/xb) and a

* after path has been applied.
* This includes:
* - Insert subtree (last) in list: -b <x0> -x <x1> -p <path>

* Example: xb := <b><c/></b>; xs := <b><d/></b>
