qemu: block: Use 'auto-read-only' instead of 'read-only' for backing chain To allow using -blockdev with blockjobs QEMU needs to reopen files in read-write mode when modifying the backing chain. To achieve this we need to use 'auto-read-only' for the backing files rather than the normal 'read-only' property. That way qemu knows that the files need to be reopened. Note that the format drivers (e.g. qcow2) are still opened with the read-only property enabled when being a member of the backing chain since they are supposed to be immutable unless a block job is started. QEMU v4.0 (since commit 23dece19da4) allows also dynamic behaviour for auto-read-only which allows us to use sVirt as we only grant write permissions to files when doing a blockjob.
