[Libguestfs] [nbdkit PATCH 2/2] common/protocol: Declare additional constants
We aren't using them yet, but as we are now publishing this file, it's
worth letting other clients have a chance to use named bits reserved
by the protocol. This does not expose anything related to resize, as
that is still experimental.
