[Qemu-devel] [PULL v5 30/43] qmp: Add deprecation information to query-machines

[Eduardo Habkost]

Export machine type deprecation status through the query-machines
QMP command.  With this, libvirt and management software will be
able to show this information to users and/or suggest changes to
VM configuration to avoid deprecated machines.
