Discarding this. Our build system is choosing only PAM auth by default when building on macOS, and I think it's a fine abstraction to use on this OS.

@NJRoadfan This is close to working now, FYI. Two outstanding issues: The directory that houses the sqlite cnid databases (e.g. `/var/lib/netatalk/CNID` needs to have 777 permissions since the database client...

~~This is on hold while I clarify the license grant for the mysql CNID module that this is based on.~~ Resolved.

@NJRoadfan @cheesestraws This is ready for initial review. Basic file operations work for me, but there are several failing spectests that need to be worked through. The sqlite backend is...

@NJRoadfan dbd -f does indeed not work still, but now with errors like ``` Jun 07 19:01:15.813359 dbd[61676] {cnid_sqlite.c:616} (error:CNID): cnid_sqlite_add: sqlite query error: datatype mismatch ```

Agreed, a migration path would be crucial for deprecating BDB. BTW, I don't think that the mysql backend supports a migration path either, does it? Anyways, I consider the migration...

I touched up `cnid_sqlite_wipe()` a bit and can confirm that the db gets wiped when invoked through dbd, but there obviously some piece missing to restore the db to a...

@NJRoadfan the `dbd -f` db wipe should be working now, although I have only tested a few trivial cases so far.
