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

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

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.

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.

in string.h was hosed for memmove/memcpy cases.

Need to sort out remaining ifnames and run testsuite.

Suggested by Jauder Ho <jauderho@transmeta.com>.

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.
