Subject: Syncprov might lose deletes (ITS#6555)
During the refresh phase the sync filter needs to be adjusted (skipping
the "(entrycsn>=cookie)" part that was inserted) when checking whether a
change needs to be replicated, otherwise we lose DELETES that happen during
the refresh phase.

Subject: slapd modrdn crash (ITS#6570)
part #1 reject RDNs with binary BER values
part #2 reject RDNs with empty values
Unauthenticated LDAP clients could crash the server by submitting a
specially crafted LDAP ModRDN operatoin.
Part #1:
OpenLDAP crashes with segfault during the processing of a modrdn call with
maliciously formed destination rdn string. No authentication is required to
trigger this vulnerability.
Part #2:
OpenLDAP crashes at a null pointer dereference during the processing of modrdn
call with maliciously formed destination rdn string. No authentication is
required to trigger this vulnerability.
