Adapt the file migration tests to take into account the auto-pause
feature.
The test currently has a flag 'stop_src' that is used to know if the
test itself should stop the VM. Add a new flag 'auto_pause' to enable
QEMU to stop the VM instead.. The two in combination allow us to
migrate a already stopped VM and check that it is still stopped on the
destination (auto-pause in effect restoring the original state).
By adding a more precise tracking of migration state changes, we can
also make sure that auto-pause is actually stopping the VM right after
qmp_migrate(), as opposed to the vm_stop() that happens at
migration_complete().
When resuming the destination a similar situation occurs, we use
'stop_src' to have a stopped VM and check that the destination does
not get a "resume" event.
