when necessary.

index files clean.

use in index_add_value(), but should modify value_normalize
to use a struct berval * instead of a char* pointer...

Added validation to exposed opaque data structures (BerElement, Sockbuf,
and LDAP).  Added macros BER_VALID, SOCKBUF_VALID, LDAP_VALID.
Added ber_pvt_ber_bytes() and ber_pvt_ber_remaining() macros to hide
some ber internals.  These really should be handled by ber_get_option().

First step in new schema support.

remove old Version.c

modify and modrdn.

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.

Moved db1/db.h check to the db1 marco in openldap.m4. Also added check for HAVE_DB1_DB_H for which header to include since it's only defined when using db1

"children" ACLs with "entry" ACLs (versus replacement of children
ACLs with "entry" ACLs).

so the (read id, write id) sequence is protected by li_nextid_mutex.

indexes could be hosed.

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

problem reported in IT78. Index files will still be stale if the modrdn
uses deleteoldrdn.

Move cache_return_entry_w() out of ldbm_back_add when the add is successful.
This change breaks back-bdb2, it needs equvalent changes of those in back-ldbm.

Move Debug messages outside of c_mutex.  Other LDBM cache codes
also should be streamlined.  Resultant approaches should then
be applied to back-bdb2.
