[Qemu-devel] [PATCH]USB tablet auto grab and ungrab

With this patch, automatic grab keyboard and mouse when the mouse enters the 
window, and ungrab when the mouse reachs the window edge.

I created this beacuse I want to close a window with ALT+F4 inside qemu, but I 
closed qemu window, because qemu is not grabbed.
