sna: Handle incremental uploads from PutImage 

PutImage rarely uploads the entire image inside a single request,
instead breaking up into scanline segments to fit within the protocol
limits. A few optimisations are based on detecting when we can discard
the GPU bo for an all-dirty CPU pixmap, which are useful in this case so
check for an entirely dirty pixmap following an incremental PutImage.
