Upgrade overhaul: Retiring ancient patches and fixing de-Hibernate problems

- Moved setting of txn isolation level to ControlDAO
 - Retired patches where target schema is < 100
  - Removed unreferenced patch implementations
  - Removed unreferenced DB scripts
 - Moved patch-specific queries (ACL upgrade counts) into patch-common-SqlMap.xml
 - Fixed count query result processing (max of nothing is NULL) leading to unboxing NPEs
 - All DM-modifying patches depend on DmPermissionsPatch i.e. it will normally run immediately after SQL scripts
