console: add graphic_hw_update_done()
Add a function to be called when a graphic update is done.
Declare the QXL renderer as async: render_update_cookie_num counts the
number of outstanding updates, and graphic_hw_update_done() is called
when it reaches none.
(note: this is preliminary work for asynchronous screendump support)
