changes to closing.  Need to add protection against read set races.

remove race conditions on connection close.
BROKEN: various counters for dn=monitor.
Initial testing on FreeBSD (with and without pthreads) was successfull.
Have not yet tested preemptive threading environments.
Have not built against backends other than LDBM.

SLAP_C_ACTIVE vs SLAP_C_INACTIVE.  Need to implement BINDING and CLOSING.
Added fields tracking pending (on bind) ops.  Could also be used to
implement per-connection thread limits.

support for TLS and SASL will be build.

Please inform me of any problems.

	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

Is initialized to 0 (unknown) and then set to 2 or 3 on bind.  Should
also be 0->3 if a special (or any) operation occurs before the bind.

Update slap_op to maintain dn and ndn (derived from conn->c_dn).
Update ldbm_back_bind to return actual bound dn (including rootdn)
	for use in slapd_conn.  Other backends use client dn.
Modify other codes to use ndn (normalized uppercase dn) most everywhere.
Aliasing, Suffixing and modrdn could use more work.
Applied suffixing to compare and modrdn.

of a busy wait and allow the pthread_yield within the loop to be
removed.  This was the only pthread_yield which was necessary
when usng non-preemptive threads.  As such, the configure.in
sched_yield/pthread_yield missing error can be removed from
configure.in.  If explicit yield function is missing, just provide
a no-op replacement.
Moved declaration of various slapd globals from main.c to init.c
so they can be shared with ldbm tools.

if strdup fails.  This is better than not checking, but we should
add orderly shutdown.

Most function and variable definitions are now preceded by its extern
definition, for error checking.  Retyped a number of functions, usually
to return void.  Fixed a number of printf format errors.

API changes (in ldap/include):
  Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
  for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.

A number of `extern' declarations are left (some added by protoize), to
be cleaned away later.  Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.

referral has been configured in the server.  Fix provided by Hallvard.

	adds POSIX RegEx (and removes BSD re_comp/re_exec) support.
* POSIX RegEx is not currently included in the distribution, however
	we will probably add Henry Spencer's REGEX library soon.
* ACL Group functionality is also included in this merge!

and setting of variables from Make-platform with defaults in Make-common.
