Subject: [PATCH 01/12] Issue 51076 - prevent unnecessarily duplication of the
 target entry

Bug Description:  For any update operation the MEP plugin was calling
                  slapi_search_internal_get_entry() which duplicates
                  the entry it returns.  In this case the entry is just
                  read from and discarded, but this entry is already
                  in the pblock (the PRE OP ENTRY).

Fix Description:  Just grab the PRE OP ENTRY from the pblock and use
                  that to read the attribute values from.  This saves
                  two entry duplications for every update operation
                  from MEP.
