qmp: add SUSPEND_DISK event
Emitted when the guest makes a request to enter S4 state.
There are three possible ways of having this event, as described here:
http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html
I've decided to add a new event and make it indepedent of SHUTDOWN.
This means that the SHUTDOWN event will eventually follow the
SUSPEND_DISK event.
I've choosen this way because of two reasons:
1. Having an indepedent event makes it possible to query for its
existence by using query-events
2. In the future, we may allow the user to change what QEMU should
do as a result of the guest entering S4. So it's a good idea to
keep both events separated
