[Bindings] accept simple string in string<->xmlNode converter

Some use case ask for passing simple libxml content node (i.e just an
UTF-8 string) when a method argument or a field of the xmlNode* type.
This commit add a static method in bindings/utils.c named
lasso_string_fragment_to_xmlnode which does this transform by trying to
parse an XML document then by trying to parse a well balanced XML
fragment of only one node (if there is more than one node such as in the
string " xxx <tag/> yyy ", we free the node list and return NULL).
