          CopyService and CheckOutCheckInService refactors to remove Lucene
          
          CopyService:
          
          Removed cm:source property from cm:copiedfrom aspect and replaced with a cm:original association.
          Added CQ-based APIs to query for copies
          Added APIs to support bi-directional walking of copy association
          Fixed sundry uses of cm:copiedfrom esp. all uses related to cm:workingcopy
          
          CheckOutCheckInService:
          
          Check-out now creates a source aspect cm:checkedOut with 1:1 relationship to cm:workingcopy via cm:workingcopylink
          Removed explicit use of cm:workingcopy aspect and replaced it with calls to COCI API
          
   29083: Audit tests fail when indexing is turned off.
          Also removed a getReader() call during rule evaluation, leading to a 'sub-action' read being recorded.
