/**
* Importer/exporter between the mozStorage-based bookmarks and the old-style
* "bookmarks.html"
*
* Format:
*
* Primary heading := h1
* Old version used this to set attributes on the bookmarks RDF root, such
* as the last modified date. We only use H1 to check for the attribute
* PLACES_ROOT, which tells us that this hierarchy root is the places root.
* For backwards compatability, if we don't find this, we assume that the
* hierarchy is rooted at the bookmarks menu.
* Heading := any heading other than h1
* Old version used this to set attributes on the current container. We only
* care about the content of the heading container, which contains the title
* of the bookmark container.
* Bookmark := a
* HREF is the destination of the bookmark
* FEEDURL is the URI of the RSS feed if this is a livemark.
* LAST_CHARSET is stored as an annotation so that the next time we go to
* that page we remember the user's preference.
* WEB_PANEL is set to "true" if the bookmark should be loaded in the sidebar.
* ICON will be stored in the favicon service
* ICON_URI is new for places bookmarks.html, it refers to the original
* URI of the favicon so we don't have to make up favicon URLs.
* Text of the <a> container is the name of the bookmark
* Ignored: LAST_VISIT, ID (writing out non-RDF IDs can confuse Firefox 2)
* Bookmark comment := dd
* This affects the previosly added bookmark
* Separator := hr
* Insert a separator into the current container
* The folder hierarchy is defined by <dl>/<ul>/<menu> (the old importing code
* handles all these cases, when we write, use <dl>).
*
* Overall design
* --------------
*
* We need to emulate a recursive parser. A "Bookmark import frame" is created
* corresponding to each folder we encounter. These are arranged in a stack,
* and contain all the state we need to keep track of.
*
* A frame is created when we find a heading, which defines a new container.
* The frame also keeps track of the nesting of <DL>s, (in well-formed
* bookmarks files, these will have a 1-1 correspondence with frames, but we
* try to be a little more flexible here). When the nesting count decreases
* to 0, then we know a frame is complete and to pop back to the previous
* frame.
*
* Note that a lot of things happen when tags are CLOSED because we need to
* get the text from the content of the tag. For example, link and heading tags
* both require the content (= title) before actually creating it.
