Doesn't harm, but looks a bit odd ... cheers, Gerd

Add two new IOs. QXL_IO_FLUSH_SURFACES - equivalent to update area for all surfaces, used to reduce vmexits from NumSurfaces to 1 on guest S3, S4 and resolution change (windows driver implementation is such that this is done on each of those occasions). QXL_IO_FLUSH_RELEASE - used to ensure anything on last_release is put on the release ring for the client to free.
