Bug 1331322 - Allow tagging of pseudo-implementing native anonymous content with the pseudo type at creation time

Browse source 
* Stop using a node bit for HasExplicitBaseURI
* Move MAY_HAVE_CLASS to mBoolFlags
* Add a flag to indicate that a node is native anonymous content
* Allow tagging of pseudo-implementing native anonymous content with the pseudo type at creation time, and eliminate explicit style contexts in nsIAnonymousContentCreator::ContentInfo
