Add a Q_() macro.

	* gtk/gtkintl.h (Q_): Add a Q_() macro.

	* gtk/gtkcellrendererprogress.h: Remove GTK_PROGRESS_CELL_UNKNOWN
	and GTK_PROGRESS_CELL_FAILED. With the ability the set the label,
	they are not really needed.

	* gtk/gtkcellrendererprogress.c: Use the xpad and ypad properties
	instead of hardwired padding, use Q_() for the default label,
	compute a reasonable minimal size.  (#142571, #142572, #142573,
