The first patch adds QEMU replies and as such has been aggressively snipped to deal with mailing list message size limits. Grab the unabriged version with

As noted in patch 10, the QEMU feature this series enables has not yet been accepted upstream: the relevant patches are
https://lists.gnu.org/archive/html/qemu-devel/2021-10/msg00161.html https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg07819.html
and of course this series should only be merged once those have gone in.
That said, patches 1-6 are necessary to implement the feature but also not strictly related to it, so they could be merged right away.
Changes from [v1]:
* rebased after Peter's recent changes enabling JSON for -device.
