[libvirt PATCH v3 1/4] qemu: introduce capability QEMU_CAPS_MIGRATION_BLOCKED_REASONS

From: Jonathon Jongsma <jjongsma(a)redhat.com&gt; since qemu 6.0, if migration is blocked for some reason, 'query-migrate' will return an array of error strings describing the migration blockers. This can be used to check whether there are any devices blocking migration, etc. Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com&gt; Signed-off-by: Eugenio Pérez <eperezma(a)redhat.com&gt; ---
