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)
