1) simultaneous operation of multiple active sync replication threads
2) cookie management for individual sync replication thread
(include rid=%3d to the slapd cookie command line option (-c))
- memory based session history to minimize sync traffic
- when client is covered by a session history, then
[add+delete] mode is used
- when client cookie is not covered by the history because
the cookie is too outdated and/or the history is truncated,
[add+present] mode is used
2. Sync cookie syntax : comma separated name=value pairs
- csn=yyyymmddhh:mm:ssZ#0xSSSS#r#ssssr,sid=nnn
at end of do_syncrepl; this fixes the problem of syncrepl never starting
if the master isn't up. Set sync interval to 60 seconds in persist mode;
it will retry connecting to the master when the master isn't up. Fail on
SASL at config time instead of at runtime when SASL is not enabled.

-p : promote : If the ldif file contains syncConsumerSubentries, convert
them to a single syncProviderSubentry. Its contextCSN
attribute has the largest value of the syncreplCookie
attributes of the syncConsumerSubentries.
syncProviderSubentry in the ldif file is retained.
-p -w : promote : Recalculate contextCSN based on entryCSN of each entry.
create Existing syncConsumerSubentries and syncProviderSubentry
are ignored and not added to the directory.
-r : demote : If the ldif file contains syncProviderSubentry, convert it
to a syncConsumerSubentry having the default syncrepl id
of 0. syncConsumerSubentries in the ldif file are retained.
-r -w : demote : Recalculate syncreplCookie based on entryCSN of each entry.
create Existing syncConsumerSubentries and syncProviderSubentry
are ignored and not added to the directory. The default
syncrepl id of 0 will be used for the new
syncConsumerSubentry.
-r -w -i %d[,%d]* : Using the comma separated list followed by the -i option,
it is possible to create multiple syncConsumerSubentries
having the syncrepl ids specified in the list.
syncreplCookie values of these sycnConsumerSubentries
will have the same value, either from the maximum
entryCSN value or from the contextCSN value of the
syncProviderSubentry.
