Protoized, moved extern definitions to .h files, fixed related bugs.
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.
