With this series, I pick up a suggestion Claudio has brought up in my CMM-migration series[1]. Migration tests can ask migrate_cmd to migrate them to a new QEMU process. Requesting migration and waiting for completion is hence a common pattern which is repeated all over the code base. Add a function which does all of that to avoid repetition. Since migrate_cmd currently can only migrate exactly once, this function is called migrate_once() and is a no-op when it has been called before. This can simplify the control flow, especially when tests are skipped.
