|LDIF related operations
|Find all Changes with given DN
|Find all Contents with given DN
|Find first Content with given DN
|Create Change LDIF between to LDIF contents. If any
| of input argument is not LDIFContent it returns Nothing.
| If there is not difference the Change LDIF with empty
| change list is returned.
| Unsing following strategy:
| 1. Iterate over L1 DN's and Modify / Remove Content
| 2. Iterate over L2 and Add Content not in L1
|Diff two AttrVal Records if any of provided.
| Implementation uses inefficient algorithm for large count of attributes within ContentRecord.
