d92b9d3c9e Introduction of a new Berkeley DB version 2 (!) specific backend.
BEWARE: the backend will be compiled.
        the backend will NOT be invoked, yet.
        the backend CANNOT be invoked, yet, because it is NOT yet
            integrated into the new initialization/startup environment
            of the slapd server.

216049bd12 New Frontend->Backend Interface
Separates per backend type from per backend database initialization
	and startup.  Also supports per type / per backend shutdown.
New frontend startup/shutdown routines are also provided:
	slap_init() slap_startup() slap_shutdown() slap_destroy()
New frontend->backend startup/shutdown is managed by:
	backend_init() backend_startup() backend_shutdown backend_destroy
backend_init() now calls bi_init() to initial all function pointers
for the backend (excepting bi_init() which is now the only hardcoded
entry point).  New entry points are detailed in slap.h struct
backend_info.  backend_info is a per database type structure.
Besides the new startup/shutdown entry points, the new interface
also supports per backend type configuration options.  One could have:

	backend bdb2	(new Berkeley DB 2 backend)
	bdb2_home	/directory

	database bdb2
	...

	*** This code is fairly experimental ***
	*** Much cleanup and testing is still needed ***

see slap.h for details on struct backend_db and backend_info.

366701bdf7 Fix dbcache/entry lock deadlock. If dbcache lock is held, it's
okay to read and write LDBM specific fields (state, refcnt,
LRU.  The id field, though is read-only once set.
cache_find_entry_dn2id(), hence, does not require any entry locks.
cache_find_entry_id() must do a entry_rdwr_trylock() and back
off if busy.
Add new rdwr lock code with trylock() functionality.
Implement entry_rdwr_trylock().

3e48937ac8 Fix idl_firstid to return NOID when !(nids > 1) instead of when (nids == 1)
Fix idl_nextid not to skip an ID if ID not in list.
Both of these should not occur if used correctly, but cheap insurance
against incorrect usage is welcomed.

72ba4cfb71 Use -lldap_r instead of -lldap -lthread.
Likely broke things for non-posix threadings....

Update -lldap_r implementation to:
	remove attribute support
	hide thread detachment
	provide concurrency accessors
	provide initialization function
	fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread

bd6dfe333d LDBM/back-ldbm locking reworked!
back-ldbm was using a cache specific lock to protect non-reentrant
	database routines from being reenterred.  This is inadequate.
	Also, reentrant database systems calls were serialized unnecessarily.

	Non-reentrant database calls must have a big_mutex.  Implemented
	this within -lldbm itself.  library requires ldbm_initialize()
	be called before any other ldbm call to initialize the big_mutex
	and to do any other db specific initialization (ie: such as
	required for DB2).

The dbc_mutex, dbc_cv, & dbc_readers fileds of dbcache are history.
The "reentrant_database" (REENTRANT_DATABASE) define is also axed.

f1e934effb Hide allocate of reentrant_database cond varible and reader count
behind REENTRANT_DATABASE.  rename reentrant_database -> REENTRANT_DATABASE.
When REENTRANT_DATABASE is defined, the simple lock is replaced
with a simple reader/writer lock.  This functionality should be removed
from back-ldbm to libldbm.

3c67248a65 cache_set_state( cache, e, 0) cannot occur before lock on parent/root
is released.  Some other thread may have cache locked but blocking
on parent.  Must give up parent lock before acquiring cache lock.
