ol_link_sasl vs ol_link_spasswd is confusing.

Fix --disable-spasswd

against Cyrus SASLdb.  Like other cleartext mechanisms,
should be protected from eavesdropping.

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

plus these changes unhidden changes:
	remove now meaning --enable-discreteaci configure option
	fix ITS#451, slapd filters
	Add ber_bvecadd() to support above
	constify ldap_pvt_find_wildcard() and misc slapd routines
	renamed some slap.h macros
	likely broken something

one can select NDBM as NDBM is not supported.

under "auto" selection.  If not auto, just warn.
Rebuild configure using appropriate tools.

simple bind via:

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.

support for DCE slash-delimited, left-to-right DNs;
support for a domain socket transport (enable with
--enable-ldapi); and extensions to URL parsing to
support the latter transport.

manual push bytes about.  Allows ber_*_t to be any 32-bit or
larger type.  Reworked AC_{HTON,NTOH}{L,S} macros to care only
about 32-bit (netlong) and 16-bit (netshort) reordering as
needed for BSD socket interface.

Select appropriopriate hton{s,l} function to use in lber-int.h.

an integer type of exactly 32 bits.

enables if MINGW32 and always enables if MINGW32).

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

replaced with actual functional tests.  Needed to provide uWin
and other Unix on NT environments.

avoid having to define macros by hand in acconfig.h (which
were mistaken added to portable.h.in).

  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).

  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

Add substitution of WRAP_LIBS

  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
