directfb: Discard long broken code and return to basics

Browse source 
Rewrite the directfb backend as nothing more than a simpler image
compositor onto a shadowfb that is flushed back to the dfb surface as
required. Future refinements would be to add damage tracking, and to mix
the useful directfb operations (such as solid fills and alpha blends).
