Create a new parser (PrototypeDocumentParser) and content sink
(PrototypeDocumentContentSink) that can be used by both XUL and XHTML.
The new parser moves the code from XULDocument that handles creating and
loading a nsXULPrototypeDocument from either the cache or the source
file. Once the parser has finished loading the prototype it notifies the
content sink. The parser is largely a stub and would be better suited
for use as a nsBaseParser, but nsHTMLDocument unfortunately needs an
nsIParser.
The new content sink has the XULDocument code responsible for the
prototype traversal that creates the DOM (XULDocument::ResumeWalk and
friends) and fires off various events.
To unify XUL and XHTML, the XHTML readystate event sequence is used in
XUL. However, the layout path of XHTML loaded from the prototype cache
more closely follows XUL, where frame initializers and layout don't
start until the entire DOM is built.
