Ralph Castain c4c9bc1573 As per the RFC: 
http://www.open-mpi.org/community/lists/devel/2014/04/14496.php

Revamp the opal database framework, including renaming it to "dstore" to reflect that it isn't a "database". Move the "db" framework to ORTE for now, soon to move to ORCM

This commit was SVN r31557.
