This will break the build of each individual patch, which will break git bisect. Each individual patch should build when applied. To fix that, you can add the new function and only drop the current one when the full conversion is done. The temporary duplication is ok.

There is no standard format when formatting info_str, so it is difficult to extract information and transmit it over QMP. This patch changes info_str from a simple string to a QDict. Patches that convert the devices to this new format will follow.
