removed "default" system for password database api: all functions must

be supported.  there are some stub routines in passdb.c which can be
copied into a password database api which do conversion.  the module
writer can choose which of these to provide full support for instead
of using the conversion routines.
(This used to be commit d906ac5941fa22f93a38d65906b89a80f971b83c)
