[libvirt] [PATCH 0/2] Add function to check cdrom status

In libvirt, it gives general Input/Output error when reading a not ready cdrom. This error could be more detailed on cdrom, such as drive not ready, no disc, trey open, no information. These patches provide private API virFileCdromStatus to check cdrom storage backend status and improve error handling of virStorageBackendVolOpen on cdrom.
