In order to mirror a server with per-object filtering, the client needs to track which server callbackID is servicing the client callback. This patch introduces the notion of a serverID, as well as the plumbing to use it for network events, although the actual complexity of using per-object filtering in the remote driver is deferred to a later patch. * src/conf/object_event.h (virObjectEventStateEventID): Add parameter. (virObjectEventStateQueueRemote, virObjectEventStateSetRemote): New prototypes. (virObjectEventStateRegisterID): Move... * src/conf/object_event_private.h: ...here, and add parameter. (_virObjectEvent): Add field. * src/conf/network_event.h (virNetworkEventStateRegisterClient): New prototype. * src/conf/object_event.c (_virObjectEventCallback): Add field. (virObjectEventStateSetRemote): New function. (virObjectEventStateQueue): Make wrapper around... (virObjectEventStateQueueRemote): New function. (virObjectEventCallbackListCount): Tweak return count when remote id matching is used. (virObjectEventCallbackLookup, virObjectEventStateRegisterID): Tweak registration when remote id matching will be used. (virObjectEventNew): Default to no remote id. (virObjectEventCallbackListAddID): Likewise, but set remote id when one is available. (virObjectEventCallbackListRemoveID) (virObjectEventCallbackListMarkDeleteID): Adjust return value when remote id was set. (virObjectEventStateEventID): Query existing id. (virObjectEventDispatchMatchCallback): Require matching event id. (virObjectEventStateCallbackID): Adjust caller. * src/conf/network_event.c (virNetworkEventStateRegisterClient): New function. (virNetworkEventStateRegisterID): Update caller. * src/conf/domain_event.c (virDomainEventStateRegister) (virDomainEventStateRegisterID): Update callers. * src/remote/remote_driver.c (remoteConnectNetworkEventRegisterAny) (remoteConnectNetworkEventDeregisterAny) (remoteConnectDomainEventDeregisterAny): Likewise. (remoteEventQueue): Hoist earlier to avoid forward declaration, and add parameter. Adjust all callers. * src/libvirt_private.syms (conf/object_event.h): Drop function.
