Both the userland and the DSL interfaces support renaming only a single bookmark at a time. As of now, there is no ZCP interface to the new functionality. I am going to add it once the DSL interface passes a test of time. This change picks up support for zfs_ioc_namecheck_t::ENTITY_NAME that was added to ZoL as part of Redacted Send/Receive feature by Paul Dagnelie . This is needed to allow a bookmark name in zc_name.
