This patch introduces two CPU models, "host" and "qemu". "qemu" is used as default when running under TCG. "host" is used as default when running under KVM. "host" cannot be used without KVM. "host" is not migration-safe. They both inherit from the base s390x CPU, which is turned into an abstract class. This patch also changes CPU creation to take care of the passed CPU string and reuses common code parse_features() function for that purpose. Unknown CPU definitions are now reported. The "-cpu ?" and "query-cpu-definition" commands are changed to list all CPU subclasses automatically, including migration-safety and whether static.
