usb keyboard: add event event queue
This patch adds a event queue to the usb keyboard. This makes sure the guest will see all key events even if they come in bursts. With this patch applied sending Ctrl-Alt-Del using vncviewer's F8 menu works. Also with autosuspend enabled the first keypress on a suspended keyboard takes a little longer to be delivered to the guest because the usb bus must be resumed first. Without event queue this easily gets lost. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
