- 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the cookie is too outdated and/or the history is truncated,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

Currently discovered via a "feature", but should use a control.
Start of a control made, but needs to be better integrated (with
auto use in ldapmodify(1)).
schema engine updated (but not schema routines so things don't run yet)
nvalues mostly populated, enough for tests 0-2 to pass
schema routines needs lots of work
modify/mods codes needs lots of work
* The original code performs ( n ) normalizations
* and ( n * ( n - 1 ) / 2 ) matches, which hide
* the same number of normalizations. The new code
* performs the same number of normalizations ( n )
* and ( n * ( n - 1 ) / 2 ) mem compares, far less
* expensive than an entire match, if a match is
* equivalent to a normalization and a mem compare ...
*
* This is far more memory expensive than the previous,
* but it can heavily improve performances when big
* chunks of data are added (typical example is a group
* with thousands of DN-syntax members; on my system:
* for members of 5-RDN DNs,
members orig bvmatch (dirty) new
1000 0m38.456s 0m0.553s 0m0.608s
2000 2m33.341s 0m0.851s 0m1.003s
* Moreover, 100 groups with 10000 members each were
* added in 37m27.933s (an analogous LDIF file was
* loaded into Active Directory in 38m28.682s, BTW).
*
* Maybe we could switch to the new algorithm when
* the number of values overcomes a given threshold?

Changed AttributeDescription.{ad_cname,ad_lang} to struct berval everywhere
Deleted ad_free() everywhere
Added ad_mutex to init.c
The AttributeDescriptions are in a linked list hanging off of the
corresponding AttributeType.
