Thanks, I pushed all patches which did not rely on the new MIGRATION
event, in other words, all except the following ones:

    qemu_monitor: Wire up MIGRATION event
    qemuDomainGetJobStatsInternal: Support migration events
    qemu: Update migration state according to MIGRATION event
    qemu: Wait for migration events on domain condition
    DO NOT APPLY: qemu: Work around weird migration status changes
