Initial status bar functionality. Promote the main window's status bar

to a MainStatusBar. Add a "LabelStack" widget, which MainStatusBar uses
to duplicate features in GtkStatusbar. Make the protocol tree a
full-blown ProtoTree widget. Move main_cf_callback from main to
WiresharkApplication. Duplicate a lot of the cf callbacks as signals and
slots. Use Q_UNUSED in a few places.
