remove contrib/sdb

removed the SDB databases in contrib/sdb as they hadn't been
maintained in some time, and were no longer able to link to named
without modification.  also cleaned up contrib/README, which still
referred to contrib subdirectores that were removed already, and
linked to an obsolete URL.
