Subject: [PATCH 32/54] qemu: Use async notification for guest reboot messages

If "notify reboot on" is issued on the monitor, guest reboot events will be
shown on the monitor, prefixed with the '#' character.

[
Converted to async notifications from the original patch:

commit 06b440abc15005a273be2604a6a8532f8b044733
Author: Dor Laor <dor.laor@qumranet.com>
Date:   Tue Jul 1 16:56:47 2008 +0300

    Add reboot message for mgmt status tracking.
