devdraw: get rid of softscreen==0xa110c hack and make attachscreen() return Memdata* all screen implementations use a Memimage* internally for the framebuffer, so we can return a shared reference to its Memdata structure in attachscreen() instead of a framebuffer data pointer. this eleminates the softscreen == 0xa110c hack as we always use shared Memdata* now.
