For slapmodify to be usable on a database, that database needs to
implement the bi_tool_dn2id_get and bi_tool_entry_modify functions,
which is not the case of the back-config. I've put together a minimal
(and maybe too naive) implementation of these for back-config and
back-ldif at the above link.

Currently, there is no validation whether the modification passes
back-config checks since config_modify_internal takes a modify
operation, while bi_tool_entry_modify receives only the new version of
the entry to be modified.

Also, for slapmodify to be really useful, it would have to allow entry
deletion, for which there is no tool mode callback. To implement
deletes, do you think it is better that deletion of an entry with
children fail or delete the entire subtree? While the former seems both
easier to implement and more sensible to me, I would like your know opinion.
