Update single debug/release not to use service manager nor event manager.
Likely breaks MINGW32 port.

(excepting WIN32_LEAN_AND_MEAN).  Rework openlog/closelog use to
eliminate need for defines.

  Remove macros already in Windows headers: strdup, FD_SETSIZE
  Set HAVE_SNPRINTF and HAVE_MEMORY_H to reflect NT environment
  Moved LDAP_DIRSEP macro to ldap_config.h.in
  Moved LDAP_SIGUSR macros to ac/signal.h

to build OpenLDAP.

added lber_types.h.nt, lber_types.h.in
removal of NULLxxx internal macros (in favor of NULL).
ch_free added to slapd,slurpd/ch_malloc.c
#define free ch_free (should be removed after s/free/ch_free/g) in proto-slap.h
ch_malloc and friends use ber_memalloc and friends

	ldap_defaults.h incorporates non-generated ldapconfig.h values.
	ldap_config.h.in is new template for autoconf generated defaults
		(namely directories and paths)
	ldap_config.h.nt, NT template (must be manually copied)
	s/<ldapconfig.h>/<ldap_defaults.h>/
	s/DIRSEP/LDAP_DIRSEP/ & s/DEFAULT_/LDAP_/

Fix LDAP_MEMORY_DEBUG realloc size bug, thanks Alex.

Add extra AC_HTONL for win32 alpha.

includes single to multiple hooks changes.
ber_mem* reimplementation.
namespace glue (finally naming has not be decided upon nor implemented).
Added ldap_int_strdup to handle "internal" strdup'ing, this version uses hooks.
ldap_pvt_strdup still available for when strdup() is missing, this version
directly uses system allocators.
Updated -lldif to use ber allocators.  Items returned by ldif routines
should be ber_memfree()d as needed.

LDAP_OPT_MATCH_STRING to ldap.h and libldap/options.c.

s/VERSION/OPENLDAP_VERSION/
manually define for NT.  Should sort out mechanism for one place
updating of package/version strings.

This commit includes many changes.  All changes compile under NT but
have not been tested under UNIX.

A Summary of changes (likely incomplete):

NT changes:
	Removed lint.
	Clean up configuration support for "Debug", "Release", "SDebug",
		and "SRelease" configurations.
	Share output directories for clients, libraries,
		and slapd.  (maybe they should be combined further
		and moved to build/{,S}{Debug,Release}).
	Enable threading when _MT is defined.
	Enable debuging when _DEBUG is defined.
	Disable setting of NDEBUG under Release/SRelease.  Asserts
		are disabled in <ac/assert.h> when LDAP_DEBUG is not
		defined.
	Added 'build/main.dsp' Master project.
	Removed non-slapd projects from slapd.dsp (see main.dsp).
	Removed replaced many uses of _WIN32 macro with feature based
		macros.

ldap_cdefs.h changes
	#define LDAP_CONST const
		(see below)
	#define LDAP_F(type) LDAP_F_PRE type LDAP_F_POST
		To allow specifiers to be added before and after
		the type declaration.  (For DLL handling)

LBER/LDAP changes
	Namespace changes:
		s/lber_/ber_/ for here and there.
		s/NAME_ERROR/LDAP_NAME_ERROR/g
	Deleted NULLMSG and other NULL* macros for namespace reasons.
	"const" libraries.  Installed headers (ie: lber.h, ldap.h)
		use LDAP_CONST macro.  Normally set to 'const' when
		__STDC__.  Can be set externally to enable/disable
		'constification' of external interface.  Internal
		interface always uses 'const'.  Did not fix warnings
		in -lldif (in lieu of new LDIF parser).

	Added _ext API implementations (excepting search and bind).
		Need to implement ldap_int_get_controls() for reponses
		with controls.

	Added numberous assert() checks.

LDAP_R
	_MT defines HAVE_NT_THREADS
	Added numberous assert() checks.
	Changed ldap_pthread_t back to unsigned long.  Used cast
	to HANDLE in _join().

LDBM
	Replaced _WIN32 with HAVE_SYSLOG

ud
	Added version string if MKVERSION is not defined.  (MKVERSION
		needs to be set under UNIX).

slapd
	Made connection sockbuf field a pointer to a sockbuf.  This
		removed slap.h dependency on lber-int.h.  lber-int.h now only
		included by those files needing to mess with the sockbuf.
	Used ber_* functions/macros to access sockbuf internals whenever
		possible.
	Added version string if MKVERSION is not defined.  (MKVERSION
		needs to be set under UNIX).
	Removed FD_SET unsigned lint

slapd/tools
	Used EXEEXT to added ".exe" to routines.  Need to define EXEEXT
		under UNIX.

ldappasswd
	Added ldappasswd.dsp.  Ported to NT.  Used getpid() to seed rand().

nt_debug
	Minor cleanup.  Added "portable.h" include and used <ac/*.h> where
	appropriate.  Added const to char* format argument.

lber: ifdef'ed out lber_..set_nonblock() function because it used ioctl's.
  If it remains, it needs to be written to support various methods for
  setting non-blocking.  ioctls should probably be last choice.  configure
  could detect existance of fcntl(), ioctl(), etc.
bdb2:
  added .dsp/.dsw files and did some basic cleanup (still needs work).

Fix library/include paths for building "Release".
Create getpass() from ud's mygetpass().

Sync portable.h.nt with portable.h.in

Update NT port.

Update NT portable.h and features.h
