I suggest that eventually we should define a single file migration/client.h
which exports everything needed by the simpler clients: blockers, notifiers,
options, cpr, and state accessors

Change all migration notifiers to type NotifierWithReturn, so notifiers
can return an error status in a future patch. For now, pass NULL for the
notifier error parameter, and do not check the return value.

Pass an error object as the third parameter to "notifier with return"
notifiers, so clients no longer need to bundle an error object in the
opaque data. The new parameter is used in a later patch.

Relax the vfio blocker so it does not apply to cpr, and add a notifier that
verifies the guest is suspended.

Check the status returned by migration notifiers and report errors.
If notifiers fail, call the notifiers again so they can clean up.
None of the notifiers return an error status at this time.
