        REGRESSION: New Icon Loaders don't handle certain non-server-root URLs correctly

        * bridge/mac/FrameMac.h: Changed originalRequestURL() to virtual
        * bridge/win/FrameWin.h: Added originalRequestURL()
        * loader/icon/IconLoader.cpp:
        (IconLoader::receivedAllData): Moved the "pageURL to iconURL mapping logic" to Frame::commitIconURLToIconDatabase()
        * page/Frame.cpp:
        (WebCore::Frame::iconURL): Construct the icon URL from *only* the protocol and host of the frame's url.
        (WebCore::Frame::endIfNotLoading): Call commitIconURLToIconDatabase() if we're not kicking off an icon load
        (WebCore::Frame::commitIconURLToIconDatabase): Map the completed doc's pageURL to the iconURL
        * page/Frame.h: Added pure virtual originalRequestURL()
        * platform/win/TemporaryLinkStubs.cpp:
        (FrameWin::originalRequestURL): Added
