Commit 57ddcc23 (v0.9.11) introduced the pmwakeup event, with
an optional 'reason' field reserved for possible future expansion.
But it failed to wire the field through RPC, so even if we do
add a reason in the future, we will be unable to get it back
to the user.
Worse, commit 7ba5defb (v1.0.0) repeated the same mistake with
the pmsuspend_disk event.
As long as we are adding new RPC calls, we might as well fix
the events to actually match the signature so that we don't have
to add yet another RPC in the future if we do decide to start
using the reason field.
* src/remote/remote_protocol.x
(remote_domain_event_callback_pmwakeup_msg)
(remote_domain_event_callback_pmsuspend_msg)
(remote_domain_event_callback_pmsuspend_disk_msg): Add reason
field.
* daemon/remote.c (remoteRelayDomainEventPMWakeup)
(remoteRelayDomainEventPMSuspend)
(remoteRelayDomainEventPMSuspendDisk): Pass reason to client.
* src/conf/domain_event.h (virDomainEventPMWakeupNewFromDom)
(virDomainEventPMSuspendNewFromDom)
(virDomainEventPMSuspendDiskNewFromDom): Require additional
parameter.
* src/conf/domain_event.c (virDomainEventPMClass): New class.
(virDomainEventPMDispose): New function.
(virDomainEventPMWakeupNew*, virDomainEventPMSuspendNew*)
(virDomainEventPMSuspendDiskNew*)
(virDomainEventDispatchDefaultFunc): Use new class.
* src/remote/remote_driver.c (remoteDomainBuildEvent*PM*): Pass
reason through.
* src/remote_protocol-structs: Regenerate.
