[PATCH 2/2] Set Spice display to fullscreen if owning window is pending fullscreen

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

When you call virt_viewer_window_enter_fullscreen() on a hidden window, it
doesn't actually change its fullscreen state.  Instead, it sets up a map-event
handler to enter fullscreen after it is shown. When _set_display() is called on
a window that is pending fullscreen status, it initially sets the fullscreen
state of the display to FALSE, which can cause an unwanted resize to be sent
down to the guest.
