This patch merges the first one into second, then we'll have a single place to reference whether we need to send the configuration section. I didn't remove the MachineState.enforce_config_section field since when applying that machine property (in machine_set_property()) we haven't yet initialized global properties and migration object. Then, it's still not easy to pass that boolean to MigrationState at such an early time. A natural benefit for current patch is that now we kept the meaning of "enforce-config-section" since it'll still have the highest priority (that's what "enforce" mean I guess).
