        Make link clicking work again on Windows.

WebCore:
        This re-implements a few functions that used to be part of FrameWin in
        their new loader-based locations, and copies a few things from the Mac
        and Qt event handling code that aren't strictly necessary but are
        pretty simple.

WebKit:
        The WebKit changes are to ignore WM_MOUSEMOVED messages when the mouse
        hasn't actually moved, which were preventing clicks from actually
        getting dispatched in many cases.  It's a peculiarity of Windows mouse
        handling that we receive these at all.
