Connor Kuehl 975a7bd228 block: Raise an error when backing file parameter is an empty string ... Providing an empty string for the backing file parameter like so: qemu-img create -f qcow2 -b '' /tmp/foo allows the flow of control to reach and subsequently fail an assert statement because passing an empty string to bdrv_get_full_backing_filename_from_filename() simply results in NULL being returned without an error being raised. To fix this, let's check for an empty string when getting the value from the opts list.
