This schema is largely a copy of the genetlink-legacy schema with the
following modifications:

 - change the schema id to netlink-raw
 - add a top-level protonum property, e.g. 0 (for NETLINK_ROUTE)
 - change the protocol enumeration to netlink-raw, removing the
   genetlink options.
 - replace doc references to generic netlink with raw netlink
 - add a value property to mcast-group definitions
