[libxml2] Use xmlNewDocText in xmlXIncludeCopyRange

[Nick Wellnhofer <nwellnhof src gnome org>]

commit 0aa8652e596a20e95ed334ac65cf15e6e9ec4b3b

    Use xmlNewDocText in xmlXIncludeCopyRange
    
    Otherwise, the initial node of the copy could be a text node with a
    NULL document. This results in the NULL document being propagated to
    copies of other nodes, losing information about the dictionary in which
    node data is stored, and freeing a dict-allocated string.
    
    See discussion in !175.
