The various ACL related commands are obsolete now that the QAuthZ
framework for authorization is fully integrated throughout QEMU network
services. Mark it as deprecated with no replacement to be provided.

Authorization is now provided by using 'object_add' together with
the 'tls-authz' or 'sasl-authz' parameters to the VNC server, and
equivalent for other network services.
