A subsequent round will add macros to separately handle forward declarations of variables from declaration of function prototypes.

avl_find_lin LDAP_P((Avlnode *, const void*, AVL_CMP));
Fix most `wider type truncated to int' bugs on OSF1 due to implicit decls: #include <stdlib.h> to get malloc & co various places, #include <ac/string.h> to get strlen & co in (liblutil/setproctitle.c), declare ch_malloc & co (slurp.h), avl_find_lin (avl.h), Malloc (ud/edit.c). Also changed ch_malloc & co from char* to void* functions.

avl_dup_ok LDAP_P((void*, void*));
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.
