has OpenLDAP extensions.  (This may be defined on non-OpenLDAP
implmentations that implement features of our API).
The extensions implied by this flag are TBD.

We'll put ldap_x_reference() functions in references.c

ldap_set/get_option support for controls.

Remove ldap_get_lderrno().

at runtime.

from ldap.h to ldap-int.

Updated other codes as needed.

	struct friendly (Friendly) changed to ldap_friendly (LDAPFriendly)
	  ldap_friendly friend prefix changed to 'lf_' from 'f_'
	removed mod_next field from LDAPMod (struct ldapmod)
	modified slapd to use new LDAPModList (struct ldapmodlist) struct.
Added LDAPv3 result codes to ldap.h

  -lldap_r can now be implemented...

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.

  configure generates ldap_features.h based from ldap_features.h.in
  LDAP_REFERRALS -> LDAP_API_FEATURE_OPENLDAP_V2_REFERRALS
  LDAP_DNS -> LDAP_API_FEATURE_OPENLDAP_V2_DNS

updated clients to use ldap_get/set_options
ld_options is renamed ld_booleans.  ldap-int.h has accessor macros.
updated libldap to use new accessor macros.

Rely on portable.h.

ldif2ldbm.c defaults moved to ldapconfig.h, sed no longer needed.
Changed type of lconn_lastused to time_t.
Added include <time.h> were needed.
