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.
