not assume LDAP_SIGUSR2

slurp.h:   #undef ldap_debug before a #define which conflicts with ldap-int.h.

create SECURITY_LIBS (top.mk) to order $SASL_LIBS $KRB_LIBS $TLS_LIBS
use $SECURITY_LIBS in Makefile.in's instead of $KRB_LIBS $TLS_LIBS

s/exit(0)/exit(EXIT_SUCCESS)/
add <ac/stdlib.h> where needed and other minor header adjustments

Requires FreeBSD's -lfetch...
Implementations to other URL APIs encouraged.
Probably should be moved to -llutil.

ldapsearch:
    use draft guidelines for determining when to use
    -t only writes binary attributes to files
    -tt writes all attributes to files
    output now lists URL instead of path to such files
    -T dir can be used to specify directory to create temp files in
    -V urlprefix can be used to change the URL prefix
    LDIF is now commented (can be disabled using -LL)
    LDIF now contains version attribute (can be disabled with -LLL)
LDIF:
    put interface changed to allow caller to specify how to encode
    put interface uses draft guidelines for determine when to base64 encode
    wrapping kludged to match old off by one bug
Tests:
    removed trailing space from some attributes (to avoid base64 encoding)
    enabled -LLL in defines.sh (should sed output to remove
        wrapping/comments/redundant separators)
Misc:
    updated codes outputting LDIF to use new put interface
TODO:
    handling of version attribute on input
    handling of URLs on input (ie: fetch URL)

	add MODRDN newSuperior support
	add '#' support to ldapmodify (but not slurpd and ldbm tools)

Include $(TLS_LIBS)

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_/

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.

identification strings compatible with ident(1) and what(1).
Uses $(VERSION) generated from configure.in.  rm build/version
rm old version .c files

Move all SunOS routines (ie: _sleep() and its helpers) to thr_lwp.c
so that it's internals can be 'static'.  Add 'static' to thr_lwp.c.
Add comment to LWP:  NEEDS WORK, may not compile!  Need some
SunOS user to sort out the details.  Volunteers?

need to be managed completely by -lldap_r.

the lock is acquired.  Add comments to that effect.  Remove
unnecessary busy loops from slapd/lock.c and slurpd/lock.c.

library, not header.  Eliminate need for <ac/unistd.h> to sometimes
include <fcntl.h> and/or <sys/file.h>.  Change lock API to expect
fd not FILE*.  Allows wider use and eliminates requirement that
lutil_lockf.h depencency on stdio.h.
Implemented lockf, fcntl, and flock locking in lutil/lockf.c.
Additional implementations (including no-op) may be needed.
Update slapd/lock.c and slurpd/lock.c to use new API.

Also add initial slapd .dsw/.dsp files.  Still needs work (mainly syslog).

	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

end of link.    Basic order is:
	$LDFLAGS internal-libs external-libs $LIBS $LTHREAD_LIBS

LTHREAD_LIBS is last as -lpthread (or equiv) must be last on many systems.
LIBS is next to last as some user might have put -lpthread (or equiv)
in $LIBS.
