please update all package to the same db4 version

[Farkas Levente]

hi,
it's be useful to update all packages to the same db4 version (eg: 
openldap, nss_ldap still use 4.0.14, etc..). i try to fill a bugzilla 
entry but it seems noone cares about it.
if all spec file can be accessable in somewhere, what's more if it can 
searchable than these kind of "inconsistency" can find much easily.
yours.
