Yes, please follow the example of blkdebug.c. There's no reason to have
these QemuOptsLists global as they don't make sense in a qemu config file.
Another important reason is that in order to add or remove a file
format, you don't have to change anything outside the image format
implementation, you just link an additional object file. Moving part of
it into qemu-config.c hurts the modularity.
