v1->v2:
---
* arm: commit message gib->gic (thanks Andrew)
* arm: remove unneeded {} (thanks Andrew)
* s390x: make patch less intrusive (thanks Claudio)

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.
