Rename libxml2 functions, and make parse tree format consistent with xml.el.

* xml.c: Switch to GNU indentation.
(make_dom): Change parse tree format to match xml.el.
(Fxml_parse_html_string_internal): Rename from html-parse-string.
(Fxml_parse_string_internal): Rename from xml-parse-string.

* configure.in: Announce whether libxml2 is linked to.
