[Lucid] backport fix for ITS#6458

Bug Description

The problem:

Replication fails if an attribute of a multi-value attribute entry is removed if the attribute does not have a equality matching rule defined in the schema.

The problem can be mitigated temporarily by a doing a full re-sync by removing the affected database and restarting the service to trigger a full sync.

This is fixed upstream beginning with the slapd 2.4.25 branch:

openldap-2.4.25/CHANGES: Fixed slapd syncrepl for attributes with no matching rule (ITS#6458)

For Ubuntu, this translates to the fix appearing in Oneiric:

slapd | 2.4.21-0ubuntu5.6 | lucid-updates
slapd | 2.4.23-6ubuntu6.1 | natty-updates
slapd | 2.4.25-1.1ubuntu4 | oneiric-updates

I am requesting the fix be backported at least to Lucid.

Upstream bug:


SRU Justification:

[Impact]: Serious. Replication, when used, is there for important reasons. It should not break due to a schema, even if poorly designed.
[Development Fix]: Fixed in an upstream release and thus already present since Oneiric
[Stable Fix]: lucid-proposed.debdiff, attached - patches taken from upstream git repository
[Test Case]: Attached as test_case.txt (from upstream bug; for consistency)
[Regression Potential]: looks to be minimal from looking at the patch. There appears to be a comprehensive test suite that continues to pass with this patch applied.
