Reviewed by: lkrispenz (Thanks!)
Branch: 389-ds-base-1.3.1
Fix Description: Change the single master resolve attr code to handle the
specific case of doing
add: newvalue
delete: oldvalue
Had to add a new API function - csn_compare_ext - to be able to compare CSNs
without the subsequence number.
Platforms tested: RHEL6 x86_64
Flag Day: no
Doc impact: no
