sunrpc: add netlink upcall for the auth.unix.gid cache
Add netlink-based cache upcall support for the unix_gid (auth.unix.gid)
cache, using the sunrpc generic netlink family.
Add unix-gid attribute-set (seqno, uid, gids multi-attr, negative,
expiry), unix-gid-reqs wrapper, and unix-gid-get-reqs /
unix-gid-set-reqs operations to the sunrpc_cache YAML spec and
generated headers.
Implement sunrpc_nl_unix_gid_get_reqs_dumpit() which snapshots pending
unix_gid cache requests and sends each entry's seqno and uid over
netlink.
Implement sunrpc_nl_unix_gid_set_reqs_doit() which parses unix_gid
cache responses from userspace (uid, expiry, gids as u32 multi-attr
or negative flag) and updates the cache via unix_gid_lookup() /
sunrpc_cache_update().
Wire up unix_gid_notify() callback in unix_gid_cache_template so
cache misses trigger SUNRPC_CMD_CACHE_NOTIFY multicast events with
SUNRPC_CACHE_TYPE_UNIX_GID.
