netsurf: move to public only API
And add some Node APIs: - getters: firstChild, lastChild, nextSibling, previoussibling, parentNode, parentElement, nodeName, nodeType, ownerDocument, isConnected - getters/setters: nodeValue, textContent - methods: appendChild And some test comptime optimizations on Document Signed-off-by: Francis Bouvier <francis.bouvier@gmail.com>
