Add support for another explicit IO error eventv0.8.1
This introduces a new event type VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON This event is the same as the previous VIR_DOMAIN_ID_IO_ERROR event, but also includes a string describing the cause of the event. Thus there is a new callback definition for this event type typedef void (*virConnectDomainEventIOErrorReasonCallback)(virConnectPtr conn, virDomainPtr dom, const char *srcPath, const char *devAlias, int action, const char *reason, void *opaque); This is currently wired up to the QEMU block IO error events * daemon/remote.c: Dispatch IO error events to client * examples/domain-events/events-c/event-test.c: Watch for IO error events * include/libvirt/libvirt.h.in: Define new IO error event ID and callback signature * src/conf/domain_event.c, src/conf/domain_event.h, src/libvirt_private.syms: Extend API to handle IO error events * src/qemu/qemu_driver.c: Connect to the QEMU monitor event for block IO errors and emit a libvirt IO error event * src/remote/remote_driver.c: Receive and dispatch IO error events to application * src/remote/remote_protocol.x: Wire protocol definition for IO error events * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c: Watch for BLOCK_IO_ERROR event from QEMU monitor
