	Fixes PR 30718.
	* gnu/xml/dom/ls/SAXEventSink.java: Add public accessor/mutators.
	* gnu/xml/transform/XSLURIResolver.java: Add support for custom
	  SAXSources without a backing URL or stream.

	Fixes PR 27710.
	* gnu/xml/dom/DomDocumentBuilderFactory.java: Fall back to synchronous
	  LSParser if implementation does not support asynchronous.
	* gnu/xml/stream/XMLParser.java,
	  gnu/xml/stream/XIncludeFilter.java: Use custom code instead of
	  java.net.URL to resolve to an an absolute URI, to avoid nonexistent
	  protocol handler problems.
