suspend: add infrastructure
This patch adds some infrastructure to handle suspend and resume to qemu. First there are two functions to switch state and second there is a suspend notifier: * qemu_system_suspend_request is supposed to be called when the guest asks for being be suspended, for example via ACPI. * qemu_system_wakeup_request is supposed to be called on events which should wake up the guest. * qemu_register_suspend_notifier can be used to register a notifier which will be called when the guest is suspended. Machine types and device models can hook in there to modify state if needed. * qemu_register_wakeup_notifier can be used to register a notifier which will be called when the guest is woken up. Machine types and device models can hook in there to modify state if needed. * qemu_system_wakeup_enable can be used to enable/disable wakeup events.
