implement an at_exit() handler.

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.

Used only for simple bind when dn == NULL and password != NULL.

Changes for URI spport:  New routines ldap_initialize and ldap_create; LDAPURLDesc replaces LDAPServer, LDAPURLDesc list used instead of ldo_defhost.

ldap_pvt_tls_config() was missing first param.

Replace old Id as needed (back-tcl).
Leave updating of contribWare to contributors (for now).

Use ldap_int_tblsize instead of s+1 in select.
Need to eliminate all to read(2).

Needs a bit more work.
	- global net/api timeouts are not inherited on session creation.
	- need configure check for inet_aton() (coming soon)
	- ioctl/fcntl portability issues (should share implementation
		with lber routines)

	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_/

and ripple change through -lldap.

library use:
  LBER_ macros expand to system routines.
  LDAP_ macros expand to new ber_ allocators.

Add ber_ and ldap_ memory allocators/deallocator:
  ber_ routines are wrappers of LBER_ macros.
  ldap_ routines are wrappers of ber_ routines.

Removed safe_realloc() macro from various files.  This issue
(if an issue) should be resolved across whole package.

ldapmodify.c now uses ber_ allocators to resolve ber_bvfree()
vs. WIN32 multiple heaps issue.

These changes should facilate implementation of
  ber_set_option( NULL, LBER_OPT_MEMORY_FN, ...)
and
  ldap_set_option( NULL, LDAP_OPT_MEMORY_FN, ...).

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().

prototype in ldap-int.h.

 added comments
 removed LDAP_MAX_ATTR_LEN
 removed LDAP_COMPAT* from <ldap.h> but not code.
 move LDAP_DEFAULT_REFHOPCOUNT to ldap-int.h
 added experimental options macros
 added LDAP_CONTROL_REFERRALS macros
libldap:
 Replace ld_attrbuffer with per use allocated attributed.
 ldap_first/next_attribute attributes now must be freed (as per draft).
 unifdef -DLDAP_API_FEATURE_X_OPENLDAP_V2_REFERRALS

to avoid unportable casts of integers to pointers and back.

These functions require their arguments to be in the range of `unsigned char'.

Redefine Debug macro to call ldap_log_printf(NULL, lvl, fmt, ...)
Should replace each Debug statement with direct call to ldap_log_printf
passing LDAP session if available.

Updates regarding threads and names.

environment settings.

Updated other codes as needed.

give "/foo", then it will check $HOME/foo, $HOME/./foo, then /foo.
This might not be what the installer hand it mind... but then again
may be it is.
w_userconf and w_conf both now use NULL arguments to disable conf loading.

Don't support ./.ldaprc...  can be spoofed to easily.

  This could cause problems on odd systems.  The generic
  headers should be extended as needed to include necessary
  system headers or, if necessary, make explicit declarations.
Extended ac/string.h header to look for string.h/strings.h if
  STDC_HEADERS is not defined.  Also provide basic declarations for
  str*() functions.  This could cause problems on odd systems.
Extended ac/unistd.h header to define basic declaration for misc
  functions that might be missing from headers.   This includes
  externs for getenv(), getopt(), mktemp(), tempname().
Protect fax500.h from multiple inclusion.  Moved includes of
  system/generic headers back to source files.
Made mail500 helper functions static.
Fixed includes of ctype.h, signal.h, etc. to use generics.
lutil/tempname.c: was including stdlib.h twice, one should stdio.h.
Wrapped <sys/resource.h> with HAVE_SYS_RESOURCE_H.
lber/io.c/ber_get_next(): Changed noctets back to signed.
  Used with BerRead which expects signed int as second arg and
  returns signed int.

Most function and variable definitions are now preceded by its extern
definition, for error checking.  Retyped a number of functions, usually
to return void.  Fixed a number of printf format errors.

API changes (in ldap/include):
  Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
  for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.

A number of `extern' declarations are left (some added by protoize), to
be cleaned away later.  Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.

Modified clients to reduce use of ldapconfig.h.edit.
ldap_{get,set}_option support is relatively complete.  Needs
to be extended to support other "features" of OpenLDAP.
