DLZ drivers used to be linked directly into named at compile time,
that's what was in configure.ac.

Later we added dlopen-able DLZ modules, which are built separately
and linked in at runtime (see contrib/dlz/modules and subdirectories).

For a long time both methods were available but in (I think?) 9.18 we
finally removed the old-style drivers.
