Instead of constantly keeping complaining that we need this big -blockdev things, let's start attacking individual parts of the project. Here is the first part, allowing block drivers to provide additional -drive options.
Any options that isn't processed by the block layer is passed to the driver which can use them. If it doesn't, you get an error message like today. At the end of this series you can specify: -drive file=test.qcow2,lazy_refcounts=on This doesn't include a way to specify options for backing files yet, but I don't think there's anything blocking such extensions on top.
