cache_rdn.patch

The LMDB listener code could reduce storage required for DNs in dntree. In my experiments with 1k users (create-32k-users-in-groups -n 1024) the attached patch reduced the cache size by about 1.5 percent. So it's a very small feature.

In a quick test I had the impression that this patch also works with cache data generated by the initial LMDB listener cache_dn.c code. I'm using the (largely undocumented) ldap_str2rdn function, which makes this possible as a side effect.
