In some sense, the point is that slapd's tools don't need ldbm_back_modrdn; 
maybe we'd try to put only a subset of what presently goes in
libbackends.a into the tools. The slap_mods_free() should be a very 
"basic" slapd utility.

In this case I can even duplicate the code of this function in 
back-ldbm/modrdn.c, it's 5 or 6 lines. I'll see what I can do best.
