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.)

18554e7511 Fix attribute/group to allow TXN to abort on lock failure. Save and 
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.

d6449b1d57 Experimental code that uses one locker ID per thread. Seems to work OK, 
is enabled by default. #undef BDB_REUSE_LOCKERS in back-bdb.h to disable.
Probably needs to be disabled when built with NO_THREADS.

1d9818a8da Re-introduce BDB_ID2ENTRY_PAGESIZE. Even if the index databases can get 
by on 4K pages, the id2entry database still needs more (16K).

a19a5d8c15 When using BDB_IDL_MULTI, there are no longer any issues with storing 
large IDLs. Concurrency is improved by using as small a page size as
possible. So, set the pagesize back to the default 4096 in this case.

859e283834 Experimental index management. Uncomment BDB_IDL_MULTI in back-bdb.h 
to activate. Needs to check limits in bdb_idl_insert_key, will get to
that later.

295e14bd54 Renamed BDB_ID2ENTRY_PAGESIZE to just BDB_PAGESIZE; set it on each database 
instead of just the id2entry db. It helps. I also found that tweaking the
environment (set_lg_bsize 2MB; set_cachesize 2MB) helps but those can be
taken care of in a DB_CONFIG file. Tweaked the bdb_bt_compare function; it
really only needs to be set on little-endian machines. (On big-endian machines
a lexical sort gives the same result as an integer sort.) Moved the final
checkpoint back to the dbenv_close, I think this leaves a cleaner log file.

5c7a7998a9 Set the id2entry database pagesize to BDB_ID2ENTRY_PAGESIZE to avoid 
overflow/fragmentation. (This is now 16K vs default 4K.) It turns out
that the entries' on-disk format is quite space-inefficient, storing
4 bytes per pointer or integer when typically >50% of those bytes are
zero. Oh well. It's about a 2:1 space increase over ldbm now, vs 4:1
before when all the entries were overflowing the 4K pages.
