gotwebd: simplify gotweb_render_index - drops the double loop; paginate in one go - avoid lstat + got_path_dir_is_empty for each entry: use dt_type if provided by the underlying filesystem - fixes a memleak: before `continue' we need to call gotweb_free_repo_dir ok stsp

gotwebd: use prev_disp to decide when to we've reached max_repos instead of hardcoding d_i - 2 and so expecting only "." and ".." as skipped entries, use t->prev_disp that is the number of repositories traversed until now (both skipped due to the pagination and the ones actually rendered.) ok jamsek
