I've actually already provided basic configure support for
modules.  See ./configure --help and include/portable.h.in.

Consider placing these in -llutil so that other applications can
share them.

Also, note, folks are talking about client side modules (for SASL
plugin).  Something to keep in mind.

Basically, I'd like the term "module" be not specific to the
type of dynamically loaded code.  And "backend" used to refer
to a database backend.  A "backend module" would be dynamically
loaded database backend.  We could also have various acl,
syntax, and matching-rule modules.

Hence, in slapd.conf, you would just specify a list of modules
to load (but not what services(s) they provide). The frontend
would call an initialization routine for each module.  This
function would then register the services (backend,
syntax, matching-rule, and acl it provides.

It look like your code may provide some of the separation
(of "module" from the service(s) it provides) already.
