(ITS#5748) tavl_find3(root=NULL,,,) - and pcache? - undefined values

libraries/liblutil/tavl.c:tavl_find3(NULL,,, &ret) returns an undefined value and sets ret = undefined.

I don't know if that can happen; it would be if pcache.c:add_query() does: new_cached_query = find_filter( op, qbase->scopes[query->scope], query->filter, first ); with qbase->scopes[query->scope] == NULL and not a substrings filter.

If nobody says anything I'll change tavl_find3(NULL,...) to return NULL and set ret = -1. I think a "no match" value fits better than 0 (match), even though there are two "no match" values (<0, >0).
