Subject: [PATCH] Run 'cont' on successful migration finish.

https://bugzilla.redhat.com/516187

As of qemu 0.10.6, qemu now honors the -S flag on incoming migration.
That means that when the migration completes, we have to issue a
'cont' command to get the VM running again.  We do it unconditionally
since it won't hurt on older qemu.

(cherry picked from commit d1ec4d7a5a4f50c9492137eaab4f021caa075f95)
