We need to improve the docs, and the error messages.

When using berkeley db, the only way to convert is to update the berkeley db
on-disk data by hand using the berkeley db utils (might need just the newest
one, or might need the one matching the old db version to dump, and the new
db version to restore from the dump), and THEN using the cyrus utils to
migrate from one database family to another (e.g. BDB to skiplist).
