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.
