Part of MOB-436: Cluster-wide Locking Service: Implement DB Changes and Service

- Unit test not checked in as it requires some schema change work that has been done manually
 - Moved activities DAO code and renamed data services to DAOs (as per iBatis and Wikipedia, etc)
 - DAO code should now go into org.alfresco.repo.domain...
 - DAO components are bean:xyzDAO and class:XyzDAO
 - Entity beans are XyzEntity, etc
