          focus ring fails to appear on select element after choosing item from popup

        - includes http://bugzilla.opendarwin.org/show_bug.cgi?id=9853
          improvements to select element, including some storage leak fixes

        * html/HTMLOptionElement.cpp: (WebCore::HTMLOptionElement::index): Use a const
        reference for the list items, so we don't have to copy a vector.
        * html/HTMLSelectElement.cpp:
        (WebCore::HTMLSelectElement::selectedIndex): Ditto.
        (WebCore::HTMLSelectElement::setSelectedIndex): Ditto.
        (WebCore::HTMLSelectElement::length): Ditto.
        (WebCore::HTMLSelectElement::remove): Ditto.
        (WebCore::HTMLSelectElement::value): Ditto.
        (WebCore::HTMLSelectElement::setValue): Ditto.
        (WebCore::HTMLSelectElement::stateValue): Ditto.
        (WebCore::HTMLSelectElement::restoreState): Ditto.
        (WebCore::HTMLSelectElement::appendFormData): Ditto.
        (WebCore::HTMLSelectElement::optionToListIndex): Ditto.
        (WebCore::HTMLSelectElement::listToOptionIndex): Ditto.
        (WebCore::HTMLSelectElement::recalcListItems): Made const, with the appropriate
        fields mutable.
        (WebCore::HTMLSelectElement::reset): Use a const reference for
        the list items, so we don't have to copy the vector. Remove the call to
        setSelectionChanged for the RenderMenuList case.
        (WebCore::HTMLSelectElement::notifyOptionSelected): Ditto, on both counts.
        (WebCore::HTMLSelectElement::defaultEventHandler): Call focus() before showing
        the pop-up.
        * html/HTMLSelectElement.h: The RenderMenuList class is no longer a friend.
        Changed the listItems function to return a const reference to the vector so
        it no longer copies the vector. Removed the const_cast to the call to
        recalcListItems and changed it to a const member function. Made m_recalcListItems
        mutable.
        * rendering/DeprecatedRenderSelect.cpp:
        (WebCore::DeprecatedRenderSelect::updateFromElement): Removed an unnecessary call
        to recalcListItems, which is called automatically. Use a const reference for the
        list items so we don't have to copy a vector.
        (WebCore::DeprecatedRenderSelect::layout): Ditto.
        (WebCore::DeprecatedRenderSelect::selectionChanged): Ditto.
        (WebCore::DeprecatedRenderSelect::updateSelection): Ditto.
        * rendering/RenderMenuList.cpp:
        (WebCore::RenderMenuList::RenderMenuList): Updated for renamed data members.
        (WebCore::RenderMenuList::createInnerBlock): Ditto.
        (WebCore::RenderMenuList::addChild): Ditto.
        (WebCore::RenderMenuList::removeChild): Ditto.
        (WebCore::RenderMenuList::setStyle): Ditto. Also removed code to set the style
        on the pop-up menu, because it's created with the correct style and destroyed
        before it a style change could occur.
        (WebCore::RenderMenuList::updateFromElement): Rearranged code to compute the
        maximum width in a simpler fashion, and to not bother trying to maintain
        the "selected" flags on the elements, since the HTMLSelectElement class
        takes care of that. Store the width as an int. Call setText to set the text
        based on the selected element's option text.
        (WebCore::RenderMenuList::paintObject): Don't check m_inner when setting
        up the clip -- always set up the clip.
        (WebCore::RenderMenuList::calcMinMaxWidth): Use m_optionsWidth directly
        instead of calling ceilf on m_longestWidth.
        (WebCore::RenderMenuList::showPopup): Don't use m_popupMenu to store the
        menu -- instead keep the pointer in a local variable. Get the selected
        index from the HTMLSelectElement.
        (WebCore::RenderMenuList::valueChanged): Call HTMLSelectElement::setSelectedIndex
        to do most of the work.
        * rendering/RenderMenuList.h: Renamed m_inner to m_innerBlock. Removed
        m_popupMenu, m_size, m_selectionChanged, and m_selectedIndex. Renamed
        m_longestWidth to m_optionsWidth and changed it to be an int. Removed
        unneeded override of removeLeftoverAnonymousBoxes function. Removed
        unneeded selectionChanged, setSelectionChanged, updateSelection, and
        hasPopupMenu functions. Removed extra includes.
        * rendering/RenderPopupMenu.cpp: (WebCore::RenderPopupMenu::populate):
        Change to iterate the list items instead of iterating all children
        of the select node.
        * rendering/RenderPopupMenu.h: Renamed getRenderMenuList to menuList.
        * rendering/RenderPopupMenuMac.mm:
        (WebCore::RenderPopupMenuMac::populate): Moved code to clear and create
        the pop-up here from the caller. Removed an extra retain that would cause
        the NSPopUpButtonCell to leak.
        (WebCore::RenderPopupMenuMac::showPopup): Removed unnecessary code to
        create the pop-up, which is now in populate, and also the call to the
        clear function, for the same reason. Reorganized code to make it a bit
        more readable. Removed an unnecessary if to check if frame is nil.
        Used a RefPtr to make sure we don't make a call on a frame after it's
        deleted. As part of the reorganization fixed a problem where we'd retain
        the event and then return early without releasing it in one case.
        (WebCore::RenderPopupMenuMac::addSeparator): Tweaked a little.
        (WebCore::RenderPopupMenuMac::addGroupLabel): Grouped all the code to
        manage the NSMenu at the bottom of the function.
        (WebCore::RenderPopupMenuMac::addOption): Ditto.
