Migration of pseries-2.3 doesn't have configuration section. Unfortunately,
QEMU 2.4/2.4.1/2.5 are buggy and always stream and expect the configuration
section, and break migration both ways.
This patch introduces a property which allows to enforce a configuration
section for machines who don't have one.
It can be set at startup:
-machine enforce-config-section=on
or later from the QEMU monitor:
qom-set /machine enforce-config-section on
It is up to the tooling to set or unset this property according to the
version of the QEMU at the other end of the pipe.
