tcp_close -> closesocket
  ioctl -> ioctlsocket
Modify codes to use tcp_close() instead of close() for sockets.
Modify ioctl codes to be compatible with WINSOCK.

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

Mainly updated back-bdb2, back-passwd, back-shell to use slap_get_time().

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.

by portable.h with NDEBUG undefined.  This makes assert() is always
available and automatically disables itself when LDAP_DEBUG is undefined.
I've included a basic assert() for pre-STDC compilers.  It relies on
abort() which may not actually be available.  (well replace abort()
with whatever is appropriate if and when we're faced with a pre-STDC
compiler that doesn't have assert()).

calloc(1, nelem*size) -> calloc(nelem, size)

address.  Useful for running multiple servers in a virtual hosting
environment.
Modified test001-ldif2ldbm to verify this functionality.  Assumes
localhost is 127.0.0.1.

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.

our connection table.

support for TLS and SASL will be build.

Please inform me of any problems.

These functions require their arguments to be in the range of `unsigned char'.

signals aimed at the process.

  First version with waiting on int to become 0; should be implemented
  via conditional variable...
Fix of typos.
First anchor for new bdb2 backend.

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.

needs work.

initialization after reading slapd.conf, and before starting the daemon

Don't leak abandon mutex.
Use ch_malloc and friends.

	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

introduction of pid/agrs parameters to the test-suite slapd.conf files;
creation of sub-directory test/var for storage of pid/args files during test;
update of the slapd and slapd.conf man pages.
(The change reduces dependency on ldapconfig.h, since SLAPD_PIDEXT
 and SLAPD_ARGSEXT are deleted from the code.)

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.

Removed old defines.

	pass STRING_UNKNOWN if !client_name
	pass STRING_UNKNOWN if !client_addr

- slapd's pid/args file names are based on the servers binary file names,
  providing for multiple servers beeing run on one host.
- slapd supports the -l command line parameter for selection of a
  syslog LOCAL user (-lLOCAL0 .. -lLOCAL7)
- db_appinit() is called during first ldbm_open() in DB 2.x to initialize
  DB debugging features (good to find bugs in the DB code :-)
- a patch for a non-initialized variable in DB's 2.x db_open is provided.

type 'sig_atomic_t' and marked it volatile.  Add detection to
configure to ensure sig_atomic_t and volatile are supported.

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

the exact nature of the functionality being tested.  -DNO_THREADS
does NOT have a yield select, hence the macro is not defined.
The slapd/daemon code has been changed to test both no threads
and yielding select before using a timeout of NULL.

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.

in string.h was hosed for memmove/memcpy cases.

Updated portable.h.nt.
Still having problems with tests.
