59a288abb5 Rewrite IDL block code to use simple array and accessor macros
instead of array with overlayed struct fields.  (which is inherently
non-portable).
Change maxid check in insert to be greater than or equal instead
of equal.
Use SAFEMEMCPY.

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.

0f17fac37d Implement NEXTID chunking. Obtain IDs in chunks of size
SLAPD_NEXTID_CHUNK.  Code protects NEXTID file to ensure
its equal to or greater than nextid.  Updated on close
to actual nextid.  next_id_save() could be called periodically
if desired.  Default chunk size is 32.  Define to 1 to disable
chunking.

0f76c52448 Modify Add/Delete/Modrdn operations to require write perms on
parent's "children" attribute.  Write lock parent to prevent
multiple clients making conflicting operations concurrently.
If parent doesn't exist (ie: is backend root), acquire a writer
lock (a simple mutex) on the "root."
Use -DSLAPD_CHILD_MODIFICATION_WITH_ENTRY_ACL to use the child's
"entry" acl for modrdn/delete operations.

64cd7d3346 Preliminary Fixes for ITS#24, ITS#26, and ldbm_back_add race condition.
Resolved deadlock by passing target entry to be_group and using
this if dn same as bdn.  It might actually be safer to check
entry ids instead of dns.
Resolved bogus add to cache after failed acl check by deferring
cache add until after parent/acl checks have successful been
completed.
Eliminated race condition caused by concurrent adds
of same dn by adding 'li_add_mutex' around the critical section
of code (most of ldbm_back_add).
This code is preliminary and still needs significant testing.

dacc0bfc7d Improve readability of base output in debugging.
Also, output UNKNOWN_PREFIX ('?') instead of writing a nul character
when the attribute prefix is unknown.
