        Merged fix from TOT to Safari-2-0-branch
        
        This fixes <rdar://problem/4661982> (crash in KHTMLParser::popBlock).
        
        - This patch reworks a previous fix for <rdar://problem/3524912> repro 
        crash in KHTMLParser::parseToken, due to parser's current element being 
        destroyed (www.gnnetcom.dk), along with subsequent adjustments to fix
        leaks.
        
        The previous solutions caused a ~2% performance regression on iBench HTML,
        due to RefPtr churn. The optimizations here gain back that ~2% plus ~1% more,
        for a total win of ~3% vs current TOT.
        
        The solution here is:
        (1) Don't let the parser ref document nodes -- that causes leaks.
        (2) Handle ref/deref manually, to avoid RefPtr churn. Specifically, when 
        moving a node between stacks or to/from 'current', rather than deref'ing
        and then ref'ing again, simply move the node, along with its refcount, to
        its new location, and overwrite its old location.

        when attempting to load http://www.apple.com/pro/profiles/ if you use a PAC file

        Because the garbage collector suspends a thread while marking its stack,
        mark methods must not call malloc, because they may end up stuck,
        trying to acquire the malloc lock from a suspended thread.

        The fix here is:
        (1) Use a data member rather than a dictionary to track nodes that are
        in the process of marking their subtrees.
        (2) Avoid the case wheter calling getDOMNodeForDocument might allocate
        the staticDOMNodesPerDocument dictionary.

        The fix is to mark all DOM Nodes when collecting on an alternate thread -- 
        not just the nodes that are still in a document.
        
        Previously, the DOMObjectsMarker didn't mark DOM nodes that were not in 
        a document, since we assumed such nodes would either be (a) unreachable 
        or (b) reachable, and therefore marked elsewhere. However, it seems that
        heap/stack entropy allows for (c) non-deterministically reachable by the
        conservative garbage collector. So, ironically, we need to mark
        DOM nodes that are not in a document to avoid crashing when trying to
        mark them later.

        REGRESSION: Line disappears when deleting
        
        Rewrote moveNodesAfterNode to address these problems:
        It moved nodes without preserving their style. 
        It traversed over siblings looking for a br to know when
        to stop merging.  If the br was burried inside a span, it 
        wouldn't find it.  If the text is whitespace:pre, it wouldn't
        stop.
        In theory it would crash if the "enclosingInlineElements" of the start of the
        selection to delete and the end of the selection to delete were the
        same.  We think that this will fix these:

        - fixed <rdar://problem/4118258> XML DOM trees freed prematurely unless reference held to document node (causes crash)
    
        I changed the design for how DOM nodes maintain their reference to
        the document. Instead of using DocumentPtr, an indirect reference
        which would go null in a clean way when the document is destroyed,
        they now have a different strategy.
    
        Nodes that belong to the document now hold a special kind of
        reference on the document - a "self only reference". When a
        document has no regular references but still has self-only
        references, it won't be destroyed, but it will drop all its
        children. This allows detached nodees to still have a valid
        document reference, but they won't keep the rest of the DOM alive
        or cause circular references.

        (1) To ensure thread-safe deallocation, set the "unsafe to destroy on 
        non-main threads" bit in the DOMObject constructor.

        (2) Made all binding objects inherit from DOMObject, because the
        WebCore data structures they wrap are not thread-safe. "DOMObject" is
        a slightly awkward name for things like the Window object, but the 
        DOM spec is considering adding a Window object, and creating a whole
        new base class for this purpose seemed like overkill.

        Fix for http://bugzilla.opendarwin.org/show_bug.cgi?id=6141 
        DOMCSSPrimitiveValue is always returning values in pixels when 
        using getComputedStyle:

        getFloatValue() took a unit type as a parameter, ignored it, and 
        returned m_value.num. This patch writes a second version of the 
        function that actually converts m_value.num to the specified unites 
        before returning it. Where a conversion is not required, I removed 
        the unit type from the caller so that it would go directly to the 
        inline version of the function.

        * css/css_valueimpl.cpp:
        (WebCore::CSSPrimitiveValue::computeLengthFloat): Remove type 
        parameter since a conversion is not needed.

        (WebCore::CSSPrimitiveValue::getFloatValue): This version of

        - fix <rdar://problem/4394910> calling Javascript window.close() does not trigger onbeforeunload event

        Check shouldClose() before actually scheduling a close.

        shouldClose() checks for the onbeforeunload handler, displays the onbeforeunload dialog, and returns a 
        result based on whether the user clicks "OK" or "Cancel".  In cases where the window is closed with cmd-w 
        or by clicking the red globe, shouldClose() is checked in the windowShouldClose delegate method.  Since 
        windowShouldClose isn't invoked when a window is closed with Javascript, it makes sense to add a check 
        for shouldClose() in scheduleClose(), returning early when appropriate before the chain of events that 
        closes a window even gets started.

        (WebCore::MacFrame::scheduleClose): add a check for shouldClose()

        where we resign focus on the previous node in setFocusNode.  Add isTextField on RenderObject
        as one way to distinguish from contenteditable elements - Win IE does not fire onChange for 
        contenteditable elements, so we won't either. Also, expose the dirty bit variables previously

        when deleting mail in khtml::RenderTableCell::collapsedBottomBorder() const 
        + 232

        RenderTableCell::collapsedBottomBorder() gets nextCell by calling 
        table()->cellBelow(this). In the case of the crash, cellBelow() returns 
        a pointer to a table cell that was already destroyed. cellBelow() thinks 
        that the pointer is still good because the grid of cells has not been updated 
        because all of this code is called through the hitTest and the hitTest does 
        not update the layout. The fix that I have is simply it have the hitTest call 
        updateLayout(). This is the only change in behavior. The rest of the patch 
        preserves behavior for simulated clicks. fast/events/stopPropagation-submit 
        caught this problem that arose from calling updateLayout() in the hitTest; 
        we should always have an x and y position of 0 for simulated clicks. This
