virsh: support remaining domain events
Earlier, I added 'virsh event' for lifecycle events, to get the concept approved; this patch finishes the support for all other events, although the user still has to register for one event type at a time. A future patch may add an --all parameter to make it possible to register for all events through a single call. * tools/virsh-domain.c (vshDomainEventWatchdogToString) (vshDomainEventIOErrorToString, vshGraphicsPhaseToString) (vshGraphicsAddressToString, vshDomainBlockJobStatusToString) (vshDomainEventDiskChangeToString) (vshDomainEventTrayChangeToString, vshEventGenericPrint) (vshEventRTCChangePrint, vshEventWatchdogPrint) (vshEventIOErrorPrint, vshEventGraphicsPrint) (vshEventIOErrorReasonPrint, vshEventBlockJobPrint) (vshEventDiskChangePrint, vshEventTrayChangePrint) (vshEventPMChangePrint, vshEventBalloonChangePrint) (vshEventDeviceRemovedPrint): New helper routines. (cmdEvent): Support full array of event callbacks. Signed-off-by: Eric Blake <eblake@redhat.com>
