NACK.

VIR_DOMAIN_EVENT_SUSPENDED_* is reserved for events where the domain is
in a paused state, due to virDomainSuspend.

We need a _new_ state (perhaps named pmsuspend), along with a new prefix
for events that move us into this new state (so far, we know of
guest-agent S3 requests that move us into this state, and pmwakeup that
moves us out of this state), since the state is very much distinct from
libvirt's notion of suspended (which really means paused).
