The new field will allow error handling to be configured by qdev_prop_register_global() callers: &error_fatal and &error_abort can be used to make QEMU exit or abort if any errors are reported when applying the properties. While doing it, change the error message from "global %s.%s=%s ignored" to "can't apply global %s.%s=%s".
