qemu_shutdown_requested may be interrupted by qemu_system_killed. If the latter sets shutdown_requested after qemu_shutdown_requested has read it but before it was cleared, the shutdown event is lost. Fix this by using atomic_xchg. This provides a different fix for the problem which commit15124e142attempts to deal with. That commit breaks use of ^C to drop into gdb, and so this approach is better (and15124e142can be reverted).
