Updated NT Project files (with Cyrus SASL library depend)

better library clean

  configure.in: check for AIX security library, set in AUTH_LIBS macro
  top.mk: add AUTH_LIBS macro to SECURITY_LIBS
  portable.h.in: added HAVE_AIX_SECURITY macro (via autoheader)
  passwd.c: use AIX getuserpw in chk_unix. Also fix logic in chk_unix:
  	getpwnam must always succeed for the given user. It is not a
	fatal error if getspnam returns no result for the user: On
	systems that support /etc/shadow, its usage is optional. The
	same logic applies for AIX, SCO/HP SecureWare, etc.

for executable files, not just libraries/modules. Also, the AIX linker
hardcodes -L paths by default; override this to prevent build paths from
appearing in distributed binaries.

mkdep.aix - a wrapper for AIX cc that sends dependency info to stdout so
that the standard mkdep script can operate.

are created detached by default. We need to set the thread attributes in
advance, otherwise pthread_detach will fail.

2 more steps left: add back-sql directory itself, and update Win32 build environment.

simple bind via:
	{KERBEROS}principal
Code is disabled by default (for security reasons).  Use
--enable-kpasswd to enable.  Behind SLAPD_KPASSWD.
Reworked Kerberos detection and split out KBIND as independent
feature (--disable-kbind) (LDAP_API_FEATURE_X_OPENLDAP_V2_KBIND).
KBIND depends upon detection of KRB4 (or KRB425) support.  Detection,
building with eBones (as distributed with FreeBSD 3.4) okay, but
wasn't able to test as I don't have a K4 KDC handy.
--with-kerberos has a number of detection options... most likely
don't work properly.

Add copyrights

Rework lutil_passwd routines to use struct berval instead of strings.

  with the shared libraries instead of static, defaults to no
* build/lib-shared.mk: if LINK_BINS_DYNAMIC is set we create a symlink to
  the .so and .so.# file along with the .a and .la files
* build/lib.mk: make sure the above links get removed on clean target
* build/top.mk: add define for LINK_BINS_DYNAMIC
* tests/scripts/defines.sh: add export for LD_LIBRARY_PATH so that tests will
  run without requiring installation of libraries when we use --enable-dynamic
  (LD_LIBRARY_PATH is always set, since it can't really hurt).

The loading step in slapd build was failing because of a weird
@SLAPD tag.  Removing it fixes the problem for me, but this should
be reviewed by someone who knows which @SLAPD_...@ tag was meant to
be there, if any.

  and related AC_SUBST() so that when back-tcl is compiled as a dynamic module we link
  -ltcl to the module and not slapd (this is the correct way to do this since the .la file
  handles giving the correct libs when we pass the module to it in the linker line with
  -dlopen). Also modified the perl backend in a similar way except that the PERL_CPPFLAGS
  always go to the module and never to slapd (slapd doesn't need them).
* build/mod.mk: added $(MODLIBS) to the dynamic module link line to accomodate module
  specific libraries. These should be defined in the back-*/Makefile.in file for each
  module (so far only back-tcl and back-perl need it).
* build/top.mk: modified the perl ldflags and cppflags slightly
* servers/slapd/Makefile.in: same here
* servers/slapd/back-perl/Makefile.in: added MODLIBS=$(MOD_PERL_LDFLAGS) for when we are
  using a dynamic module (problem, libtool wont allow linking static libs into a libtool
  lib, so unless perl's libs are compiled dynamic, then back-perl can't be a dynamic
  module. We need a test for this on perl and tcl).
* servers/slapd/back-tcl/Makefile.in: added MODLIBS=$(MOD_TCL_LIB)
* back-perl and back-tcl now compile

* all others: Added DESTDIR support

  libwrap was a dynamic library). Added -lwrap to new subst var WRAP_LIBS
  so we have more control over where it get's linked (dynamic libwrap
  causes problems when we link to programs that don't define certains
  globals that libwrap expects).
* build/top.mk: Added placeholder for WRAP_LIBS subst
* servers/slapd/Makefile.in: Added $(WRAP_LIBS) to the slapd and sslapd
  link command line specifically so it doesn't get thrown in with the rest
  of the LIBS.
* configure: rebuilt

If not available, LDBM uses big mutex and BDB2 is disabled.
Should add BerkeleyDB version detection...
