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.
