Changed the flag to xmlDocCopyNode (and similar routines), previously used

* tree.c: Changed the flag to xmlDocCopyNode (and similar routines),
  previously used only for recursion, to use a value of '2' to
  indicate copy properties & namespaces, but not children.
* xinclude.c: changed the handling of ranges to use the above new
  facility.  Fixes Bug 134268.
