remove common macros used in the span functions of most drivers from the individual drivers and put them in common code. It is still possible for a driver to define its own macros if it has special needs. This affects CLIPPIXEL, CLIPSPAN, HW_CLIPLOOP, HW_ENDCLIPLOOP, and for drivers using the spantmp2 template also GET_SRC_PTR and GET_DST_PTR.
