dd7003cf9f Added linearindex option for slapindex. Improves performance when database 
size exceeds dbcache size by minimizing cache thrashing.

ebc8bb0d83 Use long-lived per-thread TXNs for loading entries from DB. 
Make sure only one thread tries to load a given entry at a time.
Bump up the DB environment's max TXNs to accomodate the new TXNs.

279760a467 1. Session history support 
- 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      the cookie is too outdated and/or the history is truncated,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

76dd6bb6da Revert to previous behavior: 
always use DB_AUTO_COMMIT when opening a database, don't make it
  dependent on an in-progress transaction

  use mutex instead of DB lock for db access.

e8c58b4e7f Major API change - (SLAP_OP_BLOCKS) All request parameters are 
consolidated into the Operation structure. All reply parameters
are consolidated into the new SlapReply structure. Most operations
now have identical call signatures... Changes are not #ifdef'd,
revert to -r NO_SLAP_OP_BLOCKS if necessary to back out.

0be6cb5a67 Deleted bi_database_mutex, use DB_LOCK instead. Changed bdb_locker_id to 
lookup the threadctx if no Op * is provided. (bdb_db_cache doesn't know
its thread context when it acquires a locker ID.)

restore op->o_do_not_cache on TXN retry, bdb_group will set it if it
fails to get a lock.

349e05ff4d Added config keyword "searchstack" for setting search stack cache depth. 
Default is still 16.

Added IDL caching, modified from ITS#2182. Uses "idlcachesize" config
keyword. Code is #ifdef'd, currently defined, with default cache of 0.

919274432b Fixes for NO_THREADS 
Use a per-env locker ID
	Always set lock_detect, since we allow slapadd etc. concurrently
Also removed unused lock_detect_task code. lockdetect config keyword only
needs <policy>, no <seconds> argument.
